Revert "feat(audio): loopback feeder mode (#865)"

[byrongamatos]

Reverts #865 (squash commit 9a58a55) at the maintainer's request. Restores main to the pre-#865 state; the fix/asio-all-app-audio branch is untouched, so #865 can be reopened/re-worked and re-merged later.

Summary by CodeRabbit

• Bug Fixes

  • Simplified transitions between rendered audio, stems, and audio-element playback.
  • Improved reliability when switching audio sources or replacing the stems graph.
  • Removed unreliable screen-capture-based fallback behavior.

📝 Walkthrough

Walkthrough

The renderer bus feeder removes loopback capture and fallback state handling. Exclusive output now selects stems or element capture directly, while tests simplify the sandbox and validate single-call reevaluation paths.

Changes

Renderer bus feeder

Layer / File(s)	Summary
Simplify feeder engagement state machine static/app.js	Element capture stores its long-lived audio objects directly, and feeder reevaluation now engages only stems or element paths without loopback state or fallback handling.
Update feeder test coverage tests/js/renderer_bus_feeder.test.js	The sandbox no longer provides display-media capture; existing scenarios use single reevaluation calls, and loopback-specific tests are removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes
