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.
Workers share the pollers' Source instances for fetch(), so the httpx
clients must be closed only after the pool has stopped. Guards both
run_batch() and serve() against reintroducing the shutdown-order bug.

The condition only checked claimed jobs, but queued jobs with no
live workers also hang forever. Check live_workers == 0 regardless
of whether outstanding work is queued or claimed.
Rewrite the test to actually crash workers: patch _process to raise
a bare Exception (which _worker_loop doesn't catch), use
worker_count=1 so the single crash leaves live_workers == 0, and
assert the abort log message fires.
The drain loop in run_batch() polls counts_by_status() waiting for
queued and claimed counts to reach zero. If all worker tasks crash
(unhandled exception, OOM), claimed jobs stay claimed forever and
the loop never exits — the CLI command hangs.
Check live_workers during the drain loop. If claimed jobs exist but
no workers are alive to process them, log an error and break out.
The stranded jobs will be reaped on the next start.
