Final silent-exception sweep + ruff S110 lint guardrail — ~45 sites

Catches the silent excepts the awk-based earlier sweeps missed:

- Bare `except:` followed by `pass` (also swallows KeyboardInterrupt
  and SystemExit — actively wrong). Upgraded to `except Exception as
  e: logger.debug("...: %s", e)`. ~14 sites across connection_detect,
  soulseek_client, listenbrainz_manager, watchlist_scanner,
  youtube_client, navidrome_client, jellyfin_client, web_server.
- `except Exception:` + pass that the awk pattern missed (e.g.
  multi-line or unusual whitespace). ~31 sites across automation_engine,
  database_update_worker, music_database, spotify_client, web_server,
  others.
- 14 legitimate cleanup sites left silent with explicit `# noqa: S110`
  + comment explaining why (atexit handlers, finally-block conn.close
  calls). Logging during shutdown can itself crash because file handles
  get torn down before the handler fires.

Also enables `S110` rule in pyproject.toml so this pattern fails CI
going forward — drift fails at PR review instead of at runtime against
a wedged worker thread. Tests path keeps S110 ignored (test fixtures
legitimately use try-except-pass for cleanup).

Adds a WHATS_NEW entry to helper.js summarizing the full #369 sweep.

Verified: `python -m ruff check .` → All checks passed.
Verified: `python -m pytest tests/` → 2188 passed.

Closes #369

+        { title: 'Internal: Stop Swallowing Exceptions Silently', desc: 'github issue #369 (johnbaumb): the codebase had ~300 `except Exception: pass` blocks — and another ~30 bare `except: pass` ones — across web_server.py, every metadata client, every download/import worker, the repair jobs, and most service modules. when one of those paths failed at runtime, the failure was completely invisible: no log line, no telemetry, nothing. you\'d see "downloads stopped working after a few hours" or "enrichment never finishes" and there was nothing to grep for in app.log because the exception had been thrown straight into the void. swept all of them. converted to `except Exception as e: logger.debug("<context>: %s", e)` so failures land in the log with enough context to grep. bare `except:` cases (which also swallow KeyboardInterrupt and SystemExit — actively wrong) got upgraded to `except Exception:` first so ctrl-c works correctly. ~14 cleanup-path sites (atexit handlers, finally-block conn.close calls) were intentionally left silent with explicit `# noqa: S110` comments — logging during shutdown can itself crash because file handles get torn down before the handler fires. and added ruff S110 to the lint config so this pattern fails CI going forward — drift fails at PR review instead of at runtime against a wedged worker thread. zero behavior change to any happy path; just made the failure paths inspectable. test suite (2188 tests) green throughout the sweep.' },
         { title: 'Fix: Repair Job Card "X Findings" Badge Was Misleading After Bulk-Fix', desc: 'discord report: duplicate detector card said "372 findings" and cover art filler said "60 findings", but clicking the findings tab pending filter showed 0 — read like a bug ("findings aren\'t being created"). actual cause: job-card badge displayed `last_run.findings_created` (historical "found in last scan") which doesn\'t reflect current state when those findings have since been bulk-fixed and moved to status="resolved". fix: api response now includes `pending_findings_count` per job (current pending count from a single sql aggregation). badge now shows "X pending" when pending count > 0 (urgent red color), or "X found in last scan" with a muted grey color when pending = 0 but the last scan did surface something. user can tell at a glance whether something needs review vs whether it\'s a historical reminder. 3 new tests pin the per-job pending count helper.', page: 'stats' },
         { title: 'Fix: Downloads Stop After 2-3 Hours (slskd HTTP Timeout)', desc: 'github issue #499 (bafoed): big initial sync of spotify playlists worked for 2-3 hours then downloads silently stopped. 3 active tasks stuck in "searching" state, replaced every ~10 min by different ones, but slskd ui showed no actual searches happening. only fix was restarting the soulsync container — which would buy another 2-3 hours. root cause: `core/soulseek_client.py` constructed `aiohttp.ClientSession()` with no timeout at four sites. when slskd hung on a request (overloaded, transient network blip, internal stall), the http call blocked indefinitely — and the worker thread blocked with it. download executor only has `max_workers=3` for download workers. once 3 worker threads were wedged on hung calls, no further downloads could start. batch-level "stuck detection" (10-min) was correctly marking tasks `not_found` and trying to start replacements, but the executor pool was exhausted — replacements queued forever. fix: bounded `aiohttp.ClientTimeout` (total 120s, connect 15s, sock_read 60s) on every slskd `ClientSession` construction. legitimate metadata calls (search submission, status polls, download enqueue) finish in seconds — slskd doesn\'t stream files through these requests, so the timeout can\'t kill a real operation. when timeout fires, the request raises `asyncio.TimeoutError` which is now explicitly caught + logged + returns None to the caller (treats as a normal failure, same code path as a 5xx response). worker thread unblocks → executor pool stays healthy → downloads keep flowing. 3 new tests pin the timeout config + the `asyncio.TimeoutError` handler so future drift fails at the test boundary instead of at runtime against a wedged executor.', page: 'downloads' },
         { title: 'Fix: Library Reorganize Job Misclassified Album Tracks As Singles', desc: 'github issue #500 (bafoed): library reorganize repair job moved tracks like `Surf Curse/Surf Curse - Nothing Yet (2017)/01 - Christine F.flac` to single-template paths like `Surf Curse/Surf Curse - Christine F/Surf Curse - Christine F.flac`. root cause: the job used `is_album = (group_size > 1)` where `group_size` was the count of tracks for the same album currently sitting in the transfer folder being scanned — when only one track of an album was in transfer (rest already moved to library, or album tags varied across tracks like "Buds" vs "Buds (Bonus)"), each track became a 1-element group → all routed through single template. fix: rewrote the job to delegate to the per-album planner (`core.library_reorganize.preview_album_reorganize` / `reorganize_queue`) — the same planner the artist-detail "reorganize" modal uses. db-driven: the planner knows the album has multiple tracks regardless of how many sit in the transfer folder, so the album-vs-single classification is structurally correct. apply mode delegates to the existing reorganize queue → file move + post-processing + db update + sidecar handling all flow through one code path. only iterates albums for the ACTIVE media server (matches the artist-detail modal\'s scope) — multi-server users (plex + jellyfin etc) won\'t accidentally have the job touch the inactive server\'s files. albums missing a metadata source id get a single "needs enrichment first" finding instead of n per-track "no source" findings. dropped ~500 loc of tag-reading + transfer-walk + template logic that was duplicated against the per-album path. files in transfer with no db entry are now exclusively the orphan_file_detector\'s domain (clean separation). 12 tests pin the delegation contract.', page: 'library' },
