* feat(dashboard): comprehensive control panel with expand/collapse
- Add 13 panels: Convoys, Polecats, Sessions, Activity, Mail, Merge Queue,
Escalations, Rigs, Dogs, System Health, Open Issues, Hooks, Queues
- Add Mayor status banner and Summary/Alerts section
- Implement instant client-side expand/collapse (no page reload)
- Add responsive grid layout for different window sizes
- Parallel data fetching for faster load times
- Color-coded mail by sender, chronological ordering
- Full titles visible in expanded views (no truncation)
- Auto-refresh every 10 seconds via HTMX
* fix(web): update tests and lint for dashboard control panel
- Update MockConvoyFetcher with 11 new interface methods
- Update MockConvoyFetcherWithErrors with matching methods
- Update test assertions for new template structure:
- Section headers ("Gas Town Convoys" -> "Convoys")
- Work status badges (badge-green, badge-yellow, badge-red)
- CI/merge status display text
- Empty state messages ("No active convoys")
- Fix linting: explicit _, _ = for fmt.Sscanf returns
Tests and linting now pass with the new dashboard features.
* perf(web): add timeouts and error logging to dashboard
Performance and reliability improvements:
- Add 8-second overall fetch timeout to prevent stuck requests
- Add per-command timeouts: 5s for bd/sqlite3, 10s for gh, 2s for tmux
- Add helper functions runCmd() and runBdCmd() with context timeout
- Add error logging for all 14 fetch operations
- Handler now returns partial data if timeout occurs
This addresses slow loading and "stuck" dashboard issues by ensuring
commands cannot hang indefinitely.
