Phase 8: Eval Foundation + Quick Wins

[kpeatt]

Phase 37 (v1.7 View Royal Intelligence)

Goal: Users can rate AI answers and see richer meeting info; RAG traces provide measurement baseline for subsequent improvements.

Requirements: SRCH-03, SRCH-04, MTGX-01, MTGX-02

Success Criteria:

1. User can give thumbs up/down on any AI answer, feedback persisted
2. RAG traces (query, tools, latency, sources) logged for every AI answer
3. Meeting list shows summary cards with key decisions and topic indicators
4. Motion outcomes display as colored badges (passed/defeated/tabled/deferred)

Plans: 37-01 (RAG observability), 37-02 (Summary cards + badges)
