Chris CoutinhoandClaude Opus 4.8 44f72839ed fix(ingest): address review round 3 + SonarCloud reliability gate
- tests: make the transient-backoff progression assertion load-independent by
  bracketing the get_retry_decision call with before/after timestamps instead of
  measuring against a second datetime.now() (no freezegun dependency).
- tests: use pytest.approx for the ingest-queue-depth gauge assertions —
  SonarCloud python:S1244 (float == ) was a MAJOR reliability finding that
  tripped the new_reliability_rating quality gate.
- processor: tighten the EscalateError lazy-bind comment (file processing already
  imports the document stack via get_registry; the gating only spares the
  delete / text-doc paths and module-load time).

Deck #323.

"""Unit test for the per-tier ingest-queue-depth gauge (Deck #323).
Guards the round-2 fix: a queue that drains to empty (and so drops out of
procrastinate's ``list_queues_async``) must read 0, not its last non-zero value.
