A single abandoned "idle in transaction" session held locks on the documents table, which blocked the non-concurrent CREATE INDEX (hnsw) run inside the FastAPI lifespan. Each API restart queued another CREATE INDEX behind an advisory lock, leaving the server stuck at "Waiting for application startup." indefinitely and freezing ingestion writes. Changes: - setup_indexes(): build every index with CREATE INDEX CONCURRENTLY (non-blocking ShareUpdateExclusiveLock) under a per-session lock_timeout, and make each statement non-fatal so a contended/slow build is retried next boot instead of wedging startup. Drop leftover invalid indexes before rebuilding. - create_db_and_tables(): apply lock_timeout to extension/create_all DDL and gate the whole bootstrap behind DB_BOOTSTRAP_ON_STARTUP. - engine: set idle_in_transaction_session_timeout (asyncpg) so an abandoned transaction is reaped automatically. - config + .env.example: DB_BOOTSTRAP_ON_STARTUP, DB_DDL_LOCK_TIMEOUT_MS, DB_IDLE_IN_TX_TIMEOUT_MS.
