Re-architect document ingest from the shared NATS-glued document-processor to a per-tenant, in-process model owned by nextcloud-mcp-server (Deck #183). The MCP server now owns both sides of ingest: - Producer (api role): the scanner defers one job per changed document into the app's Postgres via procrastinate (queueing_lock dedup; no execution lock, so a crashed worker can't deadlock a doc — Qdrant upserts are idempotent). - Consumer (worker role): `nextcloud-mcp-server worker` drains the queue and runs the existing process_document pipeline; a periodic task reclaims jobs orphaned in `doing` by a crash. INGEST_QUEUE selects the transport (auto: postgres when DATABASE_URL is Postgres, else the in-process anyio queue for SQLite/dev). procrastinate manages its own tables (applied on a fresh DB at startup and by `db upgrade`). The vector-sync status surface reads job counts from Postgres in postgres mode. procrastinate + psycopg3 ship in the [postgres] extra; the app's own engine still uses asyncpg (driver unification is a follow-up handled in the rendered Helm chart). NATS JetStream, the Postgres-queue stub, the bus status subscriber, and nats-py are removed. BREAKING CHANGE: the external-NATS-ingest env vars are removed (INGEST_MODE, STATUS_BACKEND, INGEST_BUS_URL, INGEST_BUS_NUM_REPLICAS, FACT_EVENT_EMITTER). Use INGEST_QUEUE (memory|postgres) and the `worker` command instead. TENANT_ID is retained (no longer NATS-subject-charset-validated).
