Subject: [PATCH] fix(settings): 'Stille-Toleranz' steuert aktiven Endpoint,
 dB-Regler raus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Der sichtbare 'Stille-Toleranz'-Regler verstellte den toten Legacy-dB-VAD-Pfad; jetzt steuert er STT_ENDPOINT_MS (die echte Streaming-Pausen-Toleranz, 1-4s). Der obsolete 'Stille-Pegel (dB)'-Regler ist entfernt — der aktive STT nutzt adaptiven Rausch-Boden, Rauschen-als-Wort verhindert der no_speech_prob-Filter des Modells.
