feat: add band_extract audio source type for frequency band filtering
Some checks failed
Lint & Test / test (push) Failing after 29s
Details

Browse Source 
New audio source type that filters a parent source to a specific frequency
band (bass 20-250Hz, mid 250-4kHz, treble 4k-20kHz, or custom range).
Supports chaining with frequency range intersection and cycle detection.
Band filtering applied in both CSS audio streams and test WebSocket.
