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.
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`.
