The event loop function is now defined in `events.rs`, the redundant
`handle_events.rs` file is removed, and the module re‑exports are
updated
to expose `handle_events` from `events`.
Introduce a `Soundtrack` enum with Clap `ValueEnum` support and expose
it in the CLI as a `--sound-track` option. Extend `AudioCmd` with a
`ChangeSoundtrack` variant and refactor audio handling to load and cache
soundtracks per‑track using a thread‑safe `RwLock`. Update the
`handle_audio` function signature to accept the selected soundtrack,
adjust re‑exports, and modify `main` to pass the chosen soundtrack to
the audio thread. Also reposition the logging flag in the CLI
definition.
Add once_cell 1.21.4 and a Lazy‑initialized HashMap to store OGG bytes.
Replace file reads with in‑memory Cursor decoding, fix the
SoundrackParts enum typo, and derive Hash traits for it.
Introduce a `ChangePart` variant to `AudioCmd` and a `current_part`
state in
`handle_audio`. The audio sink is now created via
`DeviceSinkBuilder::from_default_device` with a fixed buffer size.
`load_audio`
now accepts a reference to `SoundrackParts`, and the player
automatically
queues the correct part when the queue becomes empty.
Rename the input event handler module and function.
Update imports, re‑exports, and main.rs to use handle_events.
Add a brief doc comment for the new function.
Add ALSA and Rodio crates to Cargo.toml and lockfile to enable audio
playback.
Update Nix expressions to include `alsa-lib` as a build input.
Refactor input event handling into a new `app::threads` module:
- Define `AppEvent` enum and `handle_input_events` function there.
- Adjust imports in `app/app.rs` and `main.rs` accordingly.
Remove the now‑unused `handle_input_events` and `AppEvent`
definitions from
`app/app.rs`.
