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)
