v0.7.0: New Connection screen revamp + full MySQL DB viewer (#10)

* docs: correct competitor comparison for DB Pro, Beekeeper, TablePlus

Research-verified the 'Why Gridline vs the alternatives' claims against
vendor docs, pricing pages, GitHub, and release notes (May 2026):

- DB Pro is an Electron app (founder-confirmed), not native; add
  TablePlus column to the comparison table
- Fix wrong cells: DB Pro has query/dashboard folders + table tags and
  CSV/JSON export on the free tier; object-explorer depth corrected for
  DB Pro (tables/views/indexes/enums) and Beekeeper
  (tables/views/routines/triggers)
- Reframe differentiators: unlimited-everything framing dropped for
  Beekeeper (free tier is already unlimited on tabs/connections/queries);
  keep DB-to-DB sync as the genuinely unique feature
- Add a dated 'Competitor reality check' section to AGENTS.md so future
  edits don't re-assert inaccurate claims

* docs: add project roadmap, link it from README and AGENTS

New ROADMAP.md is the source of truth for planned work, reflecting the
in-flight v0.7.0 connection-screen-revamp spec (new-connection flow,
full MySQL DB viewer, capability gating, Supabase/Neon presets,
SQLite path mode, tag overflow scroll, styling sweep).

Next-up scope: PostgreSQL object management CRUD with companion
features (schema CRUD, global object search, copy-as-DDL, object
dependencies) and an admin follow-up (users/roles/grants,
VACUUM/ANALYZE/REINDEX). MySQL Objects view explicitly deferred.

Queue: Redis browsing, MariaDB/TimescaleDB, PlanetScale/Turso,
query workbench upgrades (multiple result sets, query cancel,
result streaming, visual query builder), schema/data tooling,
SQLite .dump, schema diff, more export formats.

Planned: BYOK AI, website & docs, rolling UI/UX polish (incl.
onboarding tour, settings import/export, SSH key management).

README roadmap section now links to ROADMAP.md; AGENTS.md Related
Documents + Implementation Status reference it and the v0.7.0 spec.

* docs: release notes reference prod as the production branch

The repo's production branch is prod (feature branches merge back to
prod), not main. Update the release-cut instructions in the README and
the trigger comment in release.yml.

* docs: add robust bug report issue template

Structured .github/ISSUE_TEMPLATE/bug_report.md covering environment
(OS, Gridline version, install type, DB type/version, hosted provider,
connection method incl. SSH/TLS/socket), steps to reproduce, expected vs
actual, screenshots, logs, impact, and workarounds — plus a duplicate
checklist and secrets-redaction note. Referenced from the README
Contributing section.

* docs: drop in-flight branch mention from roadmap; remove unused starter assets

- ROADMAP.md no longer references the in-flight feature branch/spec
  (removed at the end anyway when the branch PRs into prod)
- Remove unused Vite/Tauri starter SVGs from public/ (no favicon or
  asset references anywhere in the app)

* test: fix stale README comparison-table regex in docs-coverage (5-col table)

* feat: shared INPUT_ROUNDING constant + bump to v0.7.0 (Task 1.1)

* fix: map SQLite file path to host field + provider host detection (Task 1.2)

* test: bump version expectation to 0.7.0 (Task 1.1 follow-up)

* feat: db capability matrix for DB viewer gating (Task 1.3)

* feat: provider tab definitions, Supabase/Neon icons + setup guides (Task 1.4)

* feat(rust): MySQL SQL builders + identifier quoting (Task 2.1)

* chore(rust): sync Cargo.lock to gridline 0.7.0

* feat(rust): MySQL db_connect (SSL + SSH tunnel) + pool variant (Tasks 2.2-2.3)

* feat(rust): MySQL execute_query with wrapped pagination + raw fallback (Task 2.4)

* feat(rust): MySQL introspection + changes-queue editing + DDL (Task 2.5)

* fix(ui): show table toolbar immediately while tab is still loading first data

* feat: gate DB viewer sidebar nav by db capabilities (Task 3.1)

* feat: guard DB viewer views by capability + Redis unsupported state (Task 3.2)

* feat(ui): 2-column provider tab grid (Task 4.1)

* feat(ui): collapsible Supabase/Neon setup guide (Task 4.2)

* feat(ui): SQLite file-path input with Browse (Task 4.3)

* feat(ui): connection metadata row (label + tags/env/folder) (Task 4.4)

* feat(ui): rework GeneralTab (URI + OR + manual) + reduce Detailed form tabs (Task 4.5)

* feat(ui): NewConnectionScreen two-stage flow; remove SimpleConnectionForm (Task 5.1)

* feat(ui): scroll connection-card tag row past 3 tags (Task 5.2)

* style: sweep form controls from rounded-full to rounded-lg (Task 5.3)

* feat(ui): EditConnectionModal parity + managed-preset SSL hint (Task 5.4)

* fix(rust): decode MySQL VARBINARY metadata columns (information_schema/SHOW) as strings

 Gridline is an **open-source, cross-platform database GUI client** for PostgreSQL (with MySQL, SQLite, and Redis to follow). It is built as a **Tauri 2.0 desktop app** — a lightweight native shell (~40MB baseline) around a React web frontend, with a Rust backend handling all database operations, CLI tool orchestration, and local persistence.
 
-**Core differentiators from commercial alternatives (DB Pro, TablePlus, etc.):**
-- No paywalls — unlimited tabs, connections, and saved queries by default
-- First-class PostgreSQL administration: `pg_dump`, `pg_restore`, DB-to-DB sync
-- Full object explorer: Functions, Triggers, Sequences, Enums, Extensions — not just tables
+**Core differentiators from commercial alternatives (DB Pro, TablePlus, Beekeeper Studio):**
+- **Everything free, nothing paywalled** — where DB Pro caps free users at 2 connections / 3 tabs / 5 saved queries, TablePlus caps at 2 open tabs + 2 windows, and Beekeeper reserves backup/restore, file import, multi-table export, ERD, and several DB connectors (Oracle, MongoDB, ClickHouse…) for paid tiers, Gridline ships the full feature set with no limits on tabs, connections, or saved queries
+- **DB-to-DB sync** — pipe-based `pg_dump` → `pg_restore` between two live connections; none of the alternatives (DB Pro, TablePlus, Beekeeper) offer direct DB-to-DB sync — they only back up to / restore from files
+- **Deeper PostgreSQL object explorer** — full detail views for Functions, Triggers, Sequences, Enums, and Extensions; Beekeeper and TablePlus show tables/views/routines/triggers but no sequences, enums, or extensions (Beekeeper can't even display routine definitions — issue #329 open since 2020), while DB Pro's tree stops at tables, views, indexes, and enums
+
+**Competitor reality check (verified 2026-05, from vendor docs/pricing/repos — keep this accurate):**
+- **DB Pro** (dbpro.app): **Electron app** (founder-confirmed on HN; launched Nov 2025) — not native despite "native macOS, Windows, Linux apps" marketing copy. Free plan = 2 connections / 5 saved queries / 3 open tabs / 2 dashboards / 2 table tags; data imports + SSH tunneling are paid-only per the pricing table/FAQ, while CSV/JSON export **does work on the free tier** (paid plans advertise "unlimited exports"; FAQ inconsistently claims "unlimited local connections"). Has query folders, dashboard folders, and table tags (roadmap 100%). No backup/restore (no pg_dump/pg_restore anywhere) and no DB-to-DB sync — the "Deeper Database Management" roadmap (indexes, users, constraints, VACUUM/ANALYZE) is still 0%. Schema tree: tables, views, indexes, relationships, and enums (since v1.6.0); MSSQL also lists stored procedures — no functions, triggers, sequences, or extensions on PG. Timeline: v1.0 Nov 2025 → v1.4 MSSQL/SSH/Keychain/Neon (Jan 2026) → v1.6 Redis/enums (Feb 2026) → self-hosted Studio (Mar 2026). Marketing overclaims ("native", Neon listed before it shipped) and known bugs (strict TLS verification blocks some Supabase pooler connections).
+- **Beekeeper Studio**: free Community edition = unlimited connections, no tab limits, saved queries, local folders (5.7+), staged Apply/Discard edits, basic query-result export. Paid-only: pg_dump/pg_restore backup/restore, file import, multi-table export, ERD, AI shell, JSON sidebar, cloud workspaces, and premium DB connectors (Oracle, MongoDB, ClickHouse, DuckDB…). Sidebar shows tables/views/matviews/routines/triggers — no sequences, enums, or extensions.
+- **TablePlus**: free = 2 open tabs / 2 windows / 2 advanced filters, but every other feature is included (incl. pg_dump/mysqldump backup GUI). No DB-to-DB sync, no ERD, no folder hierarchy. Sidebar: tables, views, functions, procedures.
 
 **Target audience:** Developers managing multiple database environments across projects (Personal, Work, Client). The workspace/folder hierarchy is a first-class concept.
