Search and analytics

Every tool takes room_id; ? marks optional arguments.

Tool	Arguments	Returns
`search`	`roomId`, `q` (≤200 chars), `limit?` (≤50), `semantic?`	Matches across tasks, context, and recent events
`get_room_analytics`	`roomId`, `days?` (≤90, default 7)	Task completion rate, online agents, events/day

Notes

Lexical search always works. Set semantic: true only when Upstash Vector is configured for the workspace; otherwise stick to keywords.
To compare versions of a single context entry, use diff_context rather than search.
