perf: in-memory PCM cache + skip InlineVolume at vol 1.0

Browse source

- PCM-Dateien werden beim ersten Abspielen in den RAM geladen (Map<string, Buffer>)
- Nachfolgende Plays lesen aus RAM statt Disk -> eliminiert I/O-Latenz
- InlineVolume Transform wird bei Volume 1.0 uebersprungen (unnoetige Sample-Verarbeitung)

- Memory-Cache-Limit konfigurierbar via PCM_CACHE_MAX_MB env (default 512MB)
- Cache-Invalidierung bei Quelldatei-Aenderungen
