What and why

The player now opens its outputs on a worker thread and reports back through the app's message channel. That covers the output picked from the outputs list (d) and the one it opens to play through at start, on the first play, or after an output goes away. Picking one, the track keeps playing through the old output. Playing a track with no output open, its file opens meanwhile and waits for the output. When no output opens, the player says it can't play, and space carries on from there. Keys still work while a slow Bluetooth or AirPlay device answers, and the last output asked for wins. App::play_file no longer returns a bool.

Loops that rekordbox marks active (PCPT status 4) now play round on their own when playback reaches them. anlz::cues reads the status, anlz::track_cues carries the flag from the .DAT's basic lists onto the .EXT's extended list, and loclib-model's analysis::Cue has a new active_loop field (default false when missing). The RPC schema and TypeScript types are regenerated.

Key events where shift comes as a modifier on a lowercase letter (CSI u, xterm's modifyOtherKeys) are now read as the capital. Q quit the player in those terminals.

Added tests:

• a slow output that doesn't hold up the UI, and the last output picked winning
• property tests for active loops, from written analysis files through to the deck
• the "mixes into" panel on the 3,886-track fixture
• a Hegel property that plays every deck key over damaged beat grids with quantize on and off

Fixes LOC-79

LOC-98 (#225) was already fixed by efb0e25 and can be closed there.

How it was tested

• cargo fmt --check, and cargo clippy --all-targets -- -D warnings for loclib-model, loclib-waveform, locallibrary and locallibrary-cli.
• cargo nextest run -p locallibrary-cli -E 'binary(locallibrary) & test(/^tui::/)': 518 pass. The output, active loop, quantize, shifted key and mixes-into tests pass; the new active loop property passed 3 x 300 cases.
• locallibrary, loclib-model and loclib-waveform filtered on active, cue, anlz and analysis: 234 pass.
• Not run: x86_64-pc-windows-msvc clippy and the full suite.

Checklist

• Tests cover the change
• For locallibrary: apps/locallibrary/CHANGELOG.md has a line under Unreleased, if people using it will notice
• The READMEs, docs/ and --help still say what the code does (apps/locallibrary/docs/rpc/ too, for a sidecar change)

Closing and reopening so CI runs on the new single-workflow CI against current main. Branch unchanged.
