feat(dashboard): Phase 3 — embedded web dashboard

- Single-file dark-theme HTML dashboard (569 lines, zero deps)
- GET / serves dashboard HTML (no auth required, token handled in JS)
- Auto-poll every 5s: health, senses, workflows
- Trigger/Kill buttons with confirmation + toast notifications
- Bearer token input persisted in localStorage
- Connection status indicator (green/red dot)
- Responsive layout for mobile
- SenseInfo gains triggers[] field, WorkflowStatus gains activeRunIds[]
- rslib copies dashboard.html to dist/
