* fix: minimal QueuePool (pool_size=1) with periodic dispose for FD safety Alternative to NullPool that keeps connection reuse for performance while preventing WAL handle accumulation: - pool_size: 10→1, max_overflow: 30→2 (3–9 FDs/user vs 30–120) - pool_recycle: 14400s→3600s (shorter recycle window) - auth_db: pool_size 5→1, max_overflow 10→2 - Periodic engine.dispose() every 30 min in cleanup scheduler — closes ALL pooled connections to release leaked WAL/SHM handles - FD monitoring every 5 min to detect regressions Benchmark: QueuePool(1) = 0.07ms/query vs NullPool = 0.29ms/query with SQLCipher. On 20-30 queries per page load, that's ~1.5ms vs ~6ms. See ADR-0004 for full rationale. * fix: clean up stale research entries before checking active count When a research thread crashes (e.g. RuntimeError outside app context), cleanup_research_resources never runs, leaving IN_PROGRESS rows in UserActiveResearch permanently. This blocks the queue since the active count never decreases. Now sweeps dead threads before counting: if a research_id is in the DB as IN_PROGRESS but its thread is no longer alive, mark it FAILED and remove from the in-memory tracking dict. * chore: demote FD monitoring log from INFO to DEBUG
