perf(core): cache AgentStore SQLite connection per project

Browse Source 
The dashboard re-instantiates AgentStore on every /api/agents request, and
each instance was opening a fresh Database — re-running schema migrations
and PRAGMA integrity_check on the full file. On a multi-hundred-MB DB that
was 3-7s per request and leaked file handles. Sharing a cached Database
keyed by rootDir reduces it to a one-time process cost.

Cache the AgentStore SQLite connection per project so the dashboard no longer reopens the database, re-runs migrations, and re-executes `PRAGMA integrity_check` on every `/api/agents` request. On large project databases this turned a sub-100ms call into multi-second latency that bled into every dashboard view fetching the agent list.
