- 0034_queue_messages.sql: per-app durable named queues. (app_id, queue_name)
is the identity tuple; no queue registry table. Partial indexes on
(claim_token IS NULL) for the dispatch hot path and (claim_token IS NOT NULL)
for the visibility-timeout reclaim scan. The queue table IS the outbox
for queue semantics — no double-buffering.
- 0035_queue_triggers.sql: widens triggers.kind CHECK to admit 'queue';
widens outbox.source_kind CHECK to admit 'invoke' (for invoke_async).
Adds queue_trigger_details(trigger_id PK, queue_name, visibility_timeout_secs,
last_fired_at). Retry policy lives on the parent triggers row — same
pattern as every other kind. One-consumer-per-queue is API-layer enforced
via pg_advisory_xact_lock (partial unique index can't span parent.app_id).
