The sessions table only grew — find_active ignored expired rows but nothing
deleted them, so lapsed sessions accumulated indefinitely.
- repo::session::delete_expired: indexed DELETE (sessions_expires_idx) returning
the reaped count.
- app::build spawns a detached hourly reaper (SESSION_GC_INTERVAL) that calls it,
independent of crawler/analysis config.
Test: delete_expired_removes_only_lapsed_sessions.
