What changed

added distinct bundled timer and alarm WAV assets
added validated timer_sound/1 and alarm_sound/1 Prolog configuration
added a Prolog sound playback module using direct mpv process execution
made timer completion play its configured sound before the desktop notification
packaged sound assets and mpv in every Prolog-capable Nix wrapper
added fake-player tests for both sound types and timer completion

Why

Timer completion produced only a desktop notification. Users need an audible signal, with a distinct alarm sound available when alarm scheduling is implemented.

Impact

Timers now play a short bundled chime. Timer and alarm audio paths can be overridden independently in config.pl; playback remains entirely in Prolog.

Validation

complete Nix gate: pytest plus every scripts/test-*.sh
nix build
WAV assets verified as mono 16-bit PCM at 44.1 kHz
