release: v0.30.0 notes + announcement; fix e2e DB-lock flake

Bump the in-app announcement to 0.30.0 (Desktop detection #196, badge #198,
doctor cache #199) and add release notes.

Fix a SQLITE_BUSY flake in thinking-block-safety.test.ts: openContextDbWritable
opened the context DB without a busy_timeout, so under loaded CI a write could
collide with the live plugin's handle and fail immediately instead of waiting.
Added PRAGMA busy_timeout = 5000, matching the other e2e tests that share the
context DB. Not a logic change; the audit fixes do not touch the tagging path
this test exercises.

+# v0.30.0
+
+Setup and doctor now recognize OpenCode Desktop installs that have no CLI, the TUI sidebar badge matches your theme again, and the doctor plugin-cache check is more reliable. Also a dependency refresh (newer OpenCode and Pi SDKs) and security updates.
+
+## Fixes
+
+- **Setup and doctor recognize OpenCode Desktop without a CLI (#196).** Installing OpenCode only through the Desktop app leaves no `opencode` binary on PATH (its server runs inside Electron), so setup reported "OpenCode not found" and refused to continue, and model discovery came up empty. Setup and doctor now detect a Desktop-only install and continue with manual model entry instead of claiming OpenCode is absent. A stock CLI installed outside PATH (for example under a version manager) is also found and used for model discovery. Thanks to @Treeed for the report.
+- **TUI sidebar badge color follows your theme again (#198).** On dark themes the Magic Context badge rendered white text while sibling badges (such as AFT) rendered the theme's own background color, so the two looked inconsistent. The badge now uses the theme background like the others, with a safety fallback for transparent-background themes so the label can never disappear. Thanks to @null-axiom for the report.
+- **`doctor` clears a stale plugin cache reliably (#199).** The cache check compared the cached plugin against the CLI's own version rather than the plugin's latest published version, so a stale `@latest` cache could survive when run through an older cached CLI. It now compares against the plugin's npm-latest, clears the versionless cache root as well, and preserves the cache (rather than clearing it) when the version check is offline. Thanks to @coleleavitt for the fix.
+
+## Maintenance
+
+- Refreshed dependencies and resolved several security advisories, including newer OpenCode (`@opencode-ai/plugin`, `@opencode-ai/sdk`) and Pi (`@earendil-works/pi-coding-agent`, `@earendil-works/pi-tui`) SDKs.
