fix/macos launch (#18)

* fix: macOS Finder launch (store path, ad-hoc signing, vendored openssl)

- Store::open was resolving 'gridline.db' relative to the working directory;
  Finder/LaunchServices launches run with cwd=/ so the .expect() panicked
  (exit 101, silent 'app does nothing') before Tauri ever started. Open the
  store under app.path().app_data_dir() in setup instead (same dir as the
  demo DB), creating the dir when needed.
- Add bundle.macOS.signingIdentity "-" + hardenedRuntime false so the
  bundler ad-hoc signs the whole bundle. Previously only the inner binary
  got Xcode 16's linker-signed signature, which macOS treats as unsigned:
  quarantined downloads showed 'damaged and can't be opened', and after
  quarantine removal LaunchServices silently refused to spawn it.
- ssh2 now builds OpenSSL vendored (feature vendored-openssl): the release
  binary previously carried an absolute LC_LOAD_DYLIB to the build machine's
  /opt/homebrew/opt/openssl@3/lib, which dyld aborted on (and hardened
  runtime library-validation rejected even when present).
- README: document the macOS first-launch paths (right-click Open / xattr
  for the damaged-error case, re-run after every upgrade).
- release.yml: update SIGNING STATUS comment to reflect ad-hoc signing.

* chore: bump 0.7.8 -> 0.7.9 (release prep)

- Version sync across package.json, src-tauri/Cargo.toml, src-tauri/tauri.conf.json
- version.test.ts / bundle-config.test.ts / docs-coverage.test.ts expect 0.7.9
- README: both download tables -> v0.7.9 asset names; new v0.7.9 changelog entry;
  tag instructions -> v0.7.9; MAINTENANCE comment updated
- AGENTS.md maintenance note example -> v0.7.9
- ROADMAP: Shipped (0.7.9) section; Next up retitled (0.8.0) TBD

+### Branch & PR workflow
+
+**Never commit or push directly to `prod`** — `prod` is protected (branch rules require a pull request). Always:
+
+1. Branch out first — `git checkout -b feat/<short-name>` (or `fix/…`, `docs/…`) from `prod`
+2. Commit and push the feature branch
+3. Open a PR into `prod` and merge it there
+
+Direct pushes to `prod` will be bypassed only in emergencies; prefer the PR path so changes land through the PR gate.
+
+### Releases
+
+Cut a release by tagging the **`prod`** branch once the PR is merged — `git tag vN.M.N && git push origin vN.M.N`. GitHub Actions (`release.yml`) builds installers for macOS (Apple Silicon + Intel), Windows, and Linux and opens a **draft** release (review + publish on GitHub).
+
+**Before tagging**, keep everything in sync:
+- Version number across `package.json`, `src-tauri/Cargo.toml`, and `src-tauri/tauri.conf.json`
+- `src/lib/version.test.ts` and `src/lib/docs-coverage.test.ts` if they assert the version
+- **README download links are static (versioned)** — both download tables (top **Download** section + **Which file should I download?**) link directly to the release-tag assets (`releases/download/v0.7.9/<file>`). tauri-action uses default versioned asset names (`Gridline_<ver>_aarch64.dmg`, `Gridline-<ver>-1.x86_64.rpm`, etc.) — update BOTH tables to the new names on every release (see the MAINTENANCE comment in README.md).
+- **Bundled pg tools:** `tauri.conf.json` `bundle.resources` lists `resources/pg_tools/*`; the `release.yml` matrix builds/downloads + checksum-verifies the static binaries before the Tauri build step.

 ## What is Gridline?
 
 Gridline is a modern, open-source database GUI client built with [Tauri 2.0](https://tauri.app), Rust, and React. It is lightweight by design (~40 MB baseline), powerful by default, and free from the paywalls that limit commercial alternatives.
 
 - **No caps** on connections, tabs, or saved queries.
 - **Deep PostgreSQL tooling** — visual `pg_dump`, `pg_restore`, and DB-to-DB sync.
+- **Backup, restore & sync for every database** — PostgreSQL, MySQL (`mysqldump` / bundled MariaDB clients), and SQLite (`.dump`), with direct DB-to-DB sync between live connections.
+- **Excel export** — CSV, JSON, SQL, Markdown, and `.xlsx` from any data grid.
+- **Cancel long-running queries** — a per-connection cancel button instead of waiting it out or killing the app.
+- **SQLite table editor** — the visual Create Table / Edit Table flow now works on SQLite too (`INTEGER PRIMARY KEY AUTOINCREMENT` instead of `serial`).
 - **Full MySQL + SQLite browsing** — connect, browse, query, and edit MySQL and SQLite the same way you do PostgreSQL.
 - **Full object explorer** — not just tables, but functions, triggers, sequences, enums, extensions, materialized views, and procedures.
 - **Interactive ER diagram** — explore relationships visually with crow's-foot cardinality notation.

 ## Recent Changes
 
-- **2026-08-04:** v0.7.0 — revamped the New Connection screen into a two-stage flow with a 6-provider grid (PostgreSQL, MySQL, SQLite, Redis, Supabase, NeonDB; managed presets ship with setup guides + SSL hints) and added full MySQL DB viewer support (connect, browse, query, inline cell editing + changes queue, DDL copy).
+<details>
+<summary>View the full changelog</summary>
+
+- **v0.7.9** — **macOS install/launch fixes**: the app's local store now opens under the OS app-data directory (a cwd-relative `gridline.db` made Finder-launched copies silently exit with a Rust panic before the UI started); macOS bundles are **ad-hoc signed at build time** (`signingIdentity "-"`), replacing the Xcode linker-only signature that macOS treated as unsigned ("damaged and can't be opened", silent Finder refusals) — users now get a standard one-time Gatekeeper prompt (see the [install notes](#installers-are-unsigned-for-now), incl. the `xattr` workaround); **OpenSSL is vendored** into the `ssh2` build so the release no longer depends on a Homebrew OpenSSL path; version bump.
+
+- **v0.7.8** — **SQLite `.dump` backup/restore** plus **backup / restore / sync for MySQL & SQLite** (mysqldump-based, system-first); **Excel (.xlsx) export** in the grid toolbar alongside CSV/JSON/SQL/Markdown; **cancel long-running queries** per connection; **settings export/import** (JSON); **Windows/Linux title bar fix** (macOS-only overlay drag strip); **SQLite table editor** (Create/Edit Table with SQLite-aware type mapping); version bump.
+
+- **v0.7.7** — PostgreSQL **roles & grants** management (create/edit/drop roles with attributes + a per-role privilege explorer across tables/sequences/routines/schemas/databases — collapsible grouped lists with GRANT/REVOKE staging) and **table maintenance** (VACUUM / ANALYZE / REINDEX from the table menu). **Create Table / Edit Table** visual editor: columns grid with type dropdowns and drag-to-reorder, single + composite primary keys, column-diff staging (ADD / DROP / RENAME COLUMN, ALTER TYPE, SET | DROP DEFAULT, SET | DROP NOT NULL — one statement per queue item), atomic column-reorder table rebuild (single transaction, preserves constraints/indexes/FKs/grants/sequences, fail-closed for triggers/RLS/inheritance/partitioning). **FK management** — multi-column composer with cross-schema references and ON DELETE/UPDATE, inlined into CREATE TABLE; **table options** (tablespace, row-level security); changes queue auto-refreshes the object tree after schema-modifying commits; version bump.
+
+- **v0.7.6** — Full PostgreSQL object management (create/edit/drop for enums, functions, procedures, triggers, sequences, extensions, views, materialized views, indexes, constraints) staged through the changes queue with generated-SQL previews; Enable Keychain toggle wired (default ON, opt-out; OFF = session-only); Objects view upgraded to the shared tabbed workspace (object detail tabs with per-type icons, inline manual query + changes queue); ⌘K object search fixes; version bump.

+- **2026-08-05:** v0.7.5 — bundled `pg_dump`/`pg_restore`/`psql` (system-first, bundled fallback) so admin features work with no separate install; schema CRUD (create/rename/drop with CASCADE + dependency warning); Cmd+K object search (current schema, all object types); copy-as-DDL for every browsable object type; `pg_depend` object-dependency view shown before destructive drops.
+- **2026-08-04:** v0.7.5 — revamped the New Connection screen into a two-stage flow with a 6-provider grid (PostgreSQL, MySQL, SQLite, Redis, Supabase, NeonDB; managed presets ship with setup guides + SSL hints) and added full MySQL DB viewer support (connect, browse, query, inline cell editing + changes queue, DDL copy).
 - **2026-08-04:** Revamped the built-in SQLite demo database with realistic e-commerce data (20 users, 24 products, 50 orders, 100 page views, 500 audit rows) and renamed it to **Gridline Demo (SQLite)**.
 - **2026-07-XX:** Added inline cell editing with a stage-first changes queue, row-detail drawer, keyboard navigation, and cell-level copy.
 - **2026-07-XX:** Added visual filter builder with drag-and-drop column palette and type-aware operators.

Users still get a one-time Gatekeeper prompt; README documents the `xattr -dr com.apple.quarantine` workaround.

-Gridline can already **browse** every PostgreSQL object type (functions, triggers, sequences, enums, extensions, views, materialized views, procedures, indexes, constraints). Next up: full **CRUD** on those objects without ever touching the Query tab.
-
-- Right-click any object → create / edit / drop with a generated-SQL preview before applying
-- Enums: add/remove values, rename types
-- Functions & procedures: edit signature + body, drop overloads by signature
-- Triggers: create/edit/disable/enable, timing + event pickers
-- Sequences: alter increment/start/min/max/cycle, restart
-- Extensions: install/uninstall, schema reassignment
-- Views & materialized views: edit definition, refresh matviews
-- Indexes & constraints: create/drop per table with column pickers
-- Staged through the changes queue (with confirmation) — never a surprise DDL
-- **Out of scope this release:** the MySQL "Objects" view stays deferred (see In the queue) — this iteration is PostgreSQL-only
-
-### Shipping alongside (companions)
-
-- **Schema CRUD** — create/rename/drop schemas from the object tree
-- **Global object search** — Cmd+K-style search across tables, functions, triggers, sequences, and extensions by name
-- **Copy as DDL for any object** — `CREATE FUNCTION` / `CREATE TRIGGER` / … via the same DDL-generation used for edit/drop previews (also covers the "Table structure export" queue item)
-- **Object dependencies** — `pg_depend`-based "what depends on this object?" view, shown before drops so nothing breaks silently
-
-### Admin follow-up (after object management)
-
-- **PostgreSQL users/roles + grants management** — create roles and set privileges from a UI (DB Pro has this at 0% on their roadmap — a differentiator to hold)
-- **Maintenance actions** — right-click table → VACUUM / ANALYZE / REINDEX
+- **SQLite `.dump` support** — match the pg_dump UX for SQLite (backup a SQLite database to a portable SQL dump, restore it back)
+- **Backup / Restore / Sync for MySQL & SQLite** — extend the pg-only tooling today: SQLite backup/restore + MySQL via `mysqldump` (system-first; decide bundling)
+- **Excel (.xlsx) export** — alongside CSV/JSON/SQL/Markdown in the grid export toolbar
+- **Cancel long-running queries** — per-connection cancel button (`pg_cancel_backend` and equivalents) instead of waiting or killing the app
+- **Settings export / import** — share theme, accent, editor options, page sizes, and defaults across machines (JSON file)
+- **Windows/Linux title bar fix** — the macOS "Overlay" drag strip (`h-7` in `App.tsx`) renders on every Tauri platform, so Windows/Linux show a blank grabbable bar between the native title bar and the page; gate the strip to macOS only (native title bar already handles dragging elsewhere)
+- **SQLite table editor (Create/Edit Table)** — the visual Create Table / Edit Table flow is PostgreSQL-only today (`tableManagement` capability + PG-flavored SQL gen in `TableForm`); extend to SQLite: SQLite-aware type mapping (no `serial` — `INTEGER PRIMARY KEY AUTOINCREMENT` instead), `TEXT`/`REAL`/`BLOB`, and ALTER TABLE limits (`ADD COLUMN` can't add PK/UNIQUE, `DROP COLUMN` needs SQLite ≥3.35)

+# v0.7.7 — Manual Smoke Checklist (release gate)
+
+> Run against a **scratch PostgreSQL** instance. Mark each item only after verifying it live in the app. This checklist gates the release after `feat/v0.7.7-next-up` squash-merges to `prod` and before tagging `v0.7.7`. Source: architectural spec §8 (verbatim).
+
+## Roles & grants
+
+- [ ] Create a role with all options (LOGIN, SUPERUSER, CREATEDB, CREATEROLE, INHERIT, REPLICATION, BYPASSRLS, CONNECTION LIMIT, VALID UNTIL, PASSWORD) + a membership grant to another role.
+- [ ] Grant / revoke each privilege class (table, sequence, routine, schema, database) from the role detail grants editor.
+- [ ] Drop a role that has dependencies — the confirm dialog lists the dependencies before executing.
+
+## Tables & relationships
+
+- [ ] Create a table with a multi-column PRIMARY KEY.
+- [ ] Edit a table: rename a column, add a column, drop a column, change a column type, change default, toggle nullable — each change stages as its own queue item with an `(i/n)` description.
+- [ ] Reorder columns → rebuild succeeds (single transaction: constraints, indexes, FKs both directions, grants, owned sequences preserved).
+- [ ] Reorder columns on a trigger-bearing table → rebuild refused with the blocker copy (fail-closed).
+- [ ] Set tablespace + row-level security via table options.
+- [ ] Create a cross-schema FK with ON DELETE CASCADE (referenced table picked from another schema).
+- [ ] Edit an FK → 2-item commit (drop + re-add) lands cleanly.
+
+## Maintenance
+
+- [ ] VACUUM, ANALYZE, REINDEX run on a table via the overflow menu — confirm dialog shows the lock-warning copy; success reports duration.
+
+## Regression
+
+- [ ] Demo SQLite database opens and behaves unaffected.
+- [ ] Stale-guard: after an external `ALTER TABLE`, editing the table in the app blocks staging with the stale guard.
