Continues the v0.8.3-dev API alignment beyond the hashfile-listing 404:
- download_left_hashes: "left" hashes are GET /v1/hashfiles/<id>
(returns uncracked ciphertexts), not the nonexistent /<id>/left.
- delete_job: DELETE /v1/jobs/<id>, not GET /v1/jobs/delete/<id>.
- start_job: POST /v1/jobs/start/<id>, not GET (route is POST-only).
- stop_job: Hashview has no stop route; raise NotImplementedError
pointing at delete_job rather than calling a phantom endpoint.
- found-hash bulk export: no such route exists (only single-hash
POST /v1/search); the best-effort merge is documented and degrades
gracefully on the expected 404.
Adds offline tests asserting start_job POSTs, delete_job uses DELETE,
and stop_job raises. Documents the release in README.
