9a58a55fe8 feat(audio): loopback feeder mode — all app audio under exclusive/ASIO (#865)
* feat(audio): loopback feeder mode — all app audio under exclusive/ASIO

Tester-confirmed (2026-07-11 log): song previews and other
plugin-private audio bypass the per-surface feeder taps and leak to the
default WASAPI device under ASIO output. Also confirmed: the element
capture path poisons itself when highway_3d already owns #audio's
one-shot MediaElementSource (InvalidStateError with _elCtx assigned
pre-throw → TypeError every later tick).

- New preferred mode 'loopback': one getDisplayMedia frame-audio capture
  (desktop main answers with the app's own frame) covers song, previews,
  and UI sounds for the whole exclusive session — engages even with no
  song loaded. Local playback silenced via suppressLocalAudioPlayback,
  page-mute IPC fallback otherwise.
- Sticky fallback to the existing stems/element surface modes when
  capture is unavailable (old desktop main, denied, Docker sphere).
- Element capture: assign module state only after the whole chain
  succeeds; close the context on failure — collision now retries clean.
- Failed engage now disables the bus and tears down loopback (no more
  bus-enabled-with-no-producer stranding).
- Tests: 12 (5 new — loopback engage/preference/mute-fallback/sticky
  fallback, collision retry).

* fix(audio): close loopback capture context on teardown (release tap worklet)

The loopback context was reused across engages (_lbCtx || new), but teardown
only stopped the stream + deactivated the tap — never closing the context or
detaching the worklet node. Each exclusive<->shared switch orphaned a live
tap worklet on the long-lived context. Use a fresh context per session and
close it on disengage. Adds a test asserting the context is closed on teardown.

bbdff4e10f refactor(server): extract the song routes into routers/song.py (R3) (#864)
Upload/delete, the catalog-metadata write-back, user-meta, overrides, gap-fill,
and the per-song info payload (11 routes) move to lib/routers/song.py with their
exclusive helpers (the atomic upload commit + the song-IO lock, the upload caps,
the gap-fill proposal builders). Bodies verbatim except @app->@router and the
seam reads: meta_db->appstate.meta_db, art_override_paths->appstate.art_override_paths,
and the scan/ingest helpers that stay in server.py (the scan lifecycle owns them)
-> new appstate seam callables: kick_scan, invalidate_song_caches, stat_for_cache,
and scan_status() (a getter — the underlying dict is reassigned). The gap-fill
MBID/ISRC regexes are reached as enrichment.X; _MULTIPART_OVERHEAD_SLACK (shared
with the staying AcoustID-identify route) moves to lib/enrichment.py beside
_ACOUSTID_MAX_UPLOAD_BYTES.

ROUTE ORDER: song_router mounts AFTER art_router — get_song_info's catch-all
`/api/song/{filename:path}` would otherwise shadow `/api/song/{path}/art*`
(Starlette matches first-registered; the :path converter is greedy).

server.py: 4,478 -> 3,692 (-786).

Verified: pyflakes clean; ORDERED route table preserves the specific-before-catch-all
invariant; full pytest 2397 passed (incl the art/cover 304 + CAA-fetch tests that
caught the shadowing before it was fixed). eslint 0.

BEHAVIORAL — needs an on-device pass (upload a sloppak, edit metadata write-back,
delete a song) before merge.
