release: bump version to 0.0.4.6

AudioTrack.stop() + release() direkt nach dem letzten write() killt die
letzten Sekunden Audio — die Samples sind zwar im Buffer, aber noch
nicht durch die Hardware rausgespielt. Deshalb brach die Sprachausgabe
mitten im Satz ab (z.B. bei "diesmal").

Fix: Writer-Thread wartet im finally-Block bis playbackHeadPosition die
Anzahl geschriebener Frames erreicht, dann erst stop()/release().
Safety: 2s Stall-Detection, falls AudioTrack haengen bleibt.

- * Streamt PCM-s16le Audio direkt via AudioTrack MODE_STREAM.
+ * Streamt PCM-s16le Audio direkt via AudioTrack MODE_STREAM mit Pre-Roll.
+ *
+ * Pre-Roll: AudioTrack wird zwar direkt gebaut und gefuttert, aber play()
+ * wird erst aufgerufen wenn PREROLL_SECONDS Audio im Buffer ist. So hat
+ * der Stream Zeit einen Vorrat aufzubauen — wenn XTTS mit RTF>1 rendert
+ * (langsamer als Echtzeit), laeuft der Buffer trotzdem nicht leer.
  *
  * Flow:
- *   JS: start(sampleRate, channels) → öffnet AudioTrack und startet Writer-Thread
- *   JS: writeChunk(base64)           → dekodiert, queued, Writer schreibt non-blocking
- *   JS: end()                         → wartet bis Queue leer, schließt AudioTrack
- *   JS: stop()                        → Hart stoppen, Queue leeren (Cancel)
- *
- * Vorteil gegenüber Sound-File-Queue:
- *   - Keine Gap zwischen Chunks (AudioTrack puffert intern)
- *   - Erste Samples beginnen zu spielen sobald der erste Chunk da ist
- *   - Kein WAV-Header-Parsing pro Chunk
+ *   JS: start(sampleRate, channels) → öffnet AudioTrack (noch nicht play())
+ *   JS: writeChunk(base64)           → dekodiert, queued, Writer schreibt
