feat: Agent Dreaming Mode — idle background reflection loop (#1019)

- Add src/timmy/dreaming.py with DreamingEngine: rule synthesis from
  session logs during idle periods with configurable wake/sleep thresholds
- Add src/dashboard/routes/dreaming.py with REST endpoints for
  dreaming status, history, and manual trigger
- Add dreaming_status.html partial template for HTMX polling
- Wire dreaming_router into dashboard app
- Add dreaming CSS styles to mission-control.css
- Add dreaming_enabled/dreaming_idle_threshold_s config settings
- 17 unit tests all passing

Fixes #1019
