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.
