refactor(agent): DRY pass on the GPU agent worker package
Consolidate genuine duplication in agent/fc_agent into single-source
helpers (behavior-preserving; DRY Pass process #594):
worker.py
- _fail(jid, image_id, exc, verb) — 4 terminal "fail this job" blocks
(downloader HTTP-fault + decode, consumer non-transient + generic).
- _release(job_ids) (was _release_owned) — the one lease hand-back path;
6 inline release([jid])+unhold sites now route through it.
- _stopped(stop_evt) + _abort_if_stopped(jid, stop_evt) — 4 stop-check
-and-release blocks and every bare stop-check.
- _timed(stage) contextmanager — ~8 monotonic()/_record() timing pairs;
records only on clean exit, matching the old skip-on-raise behavior.
- _ewma(prev, x, alpha) module fn — 3 EWMA updates in the autoscaler.
client.py
- _submit(path, payload) — submit / submit_embedding (retrying session).
- _post_quiet(path, payload) — heartbeat / fail / release fire-and-forget.
detectors.py
- Proposers._top(detector, image, cap) — merges components() and panels().
config.py
- _bool_env(name, default) — auto_start / auto_scale env parsing.
Left alone (recorded): the xyxy→norm-xywh conversion duplicated across
models.py/detectors.py (2 copies, independent wrapper modules — sharing
would couple them), and the _ensure_embedder/_ensure_proposers pair (same
lock shape, different concepts).
