haiku.rag.ingester.sources was never ingester-only: one-shot client
ingestion resolves adapters through it (create_document_from_source), and
convert() now fetches through HTTPSource, so the core client imported into
the ingester package to reach them.
Move the package to haiku.rag.sources and update every import. No shims:
haiku.rag.ingester.sources is gone.
The haiku.rag.sources plugin entry-point group is unchanged, so third-party
source packages need no edit — the group name now matches the module path it
always implied.
Source unit tests move to tests/sources/. test_source_plugins.py stays in
tests/ingester/: it drives a PeriodicPoller against the job repo, so it is
plugin wiring through ingester machinery rather than a source test.
Relocate CircuitBreaker from ingester/pollers to haiku/rag/circuit_breaker
so non-ingester callers (docling-serve provider) can reuse it without
depending on the ingester package.

Workers parked on job_available.wait() were not woken by stop(),
causing them to sleep out the full poll_idle_interval_s before
noticing _stop. With the default 1.0s interval, stop() took ~0.8s
instead of ~0.007s.
Notify all waiters on the condition in stop() so idle workers exit
immediately. Add tests for fast job pickup via notification and
fast shutdown with idle workers.
If sync.upsert() or sync.delete() raises after a job is already
marked succeeded (e.g. disk full, DB locked), the unhandled
exception crashes the worker. The job stays succeeded but sync_state
is stale, and the crashed worker stops processing other jobs.
Wrap the post-success sync_state writes in a try/except. On failure,
log the error and continue. The worst case is a redundant re-ingest
on the next sweep — better than killing the worker.
Workers previously polled the queue with a fixed 1s sleep between
claim attempts, adding ~500ms average latency to job pickup. Now
JobRepo.job_available (an asyncio.Condition) is notified on every
successful enqueue, waking idle workers immediately. The poll
interval remains as a timeout fallback for stop signals and breaker
state changes.
