Replace the hard 0/1 VAD gate with a 20ms ramp in the worklet to prevent
clicks on open/close transitions. Expose positive and negative speech
probability thresholds as user-adjustable settings (defaults 0.5/0.35).
Sliders with restore-defaults button added to the VAD section of the
audio settings tab.

Starting the gate closed caused permanent silence if the ONNX model or
WASM files failed to load (onFrameProcessed never fired). Gate now starts
open so audio flows immediately; the first silence frame closes it. Also
ensures the gate is always reset to open when VAD is disabled.

onSpeechStart/onSpeechEnd fire at segment boundaries — with constant
non-speech noise, onSpeechEnd never fires so the gate stayed open.
Switch to onFrameProcessed which fires every ~96ms and applies hysteresis
(open at >0.5, close at <0.35) matching Silero's own thresholds. Gate now
starts closed and opens only once the first speech frame is confirmed.

Integrates @ricky0123/vad-web's MicVAD as an optional voice activity detector
alongside the noise gate. When enabled, the Silero ONNX model classifies each
audio frame as speech or silence; silence frames mute the worklet's output via
a new VAD gate message. VAD is wired into Publisher.ts alongside the existing
noise gate transformer. Vite is configured to copy the worklet bundle, ONNX
model, and ORT WASM files to /vad/ so they're reachable at runtime.

Implements a per-sample transient suppressor in the noise gate AudioWorklet
that instantly cuts gain when a sudden loud peak (desk hit, mic bump) exceeds
the slow background RMS by a configurable threshold, then releases over a
short window. Exposes enable, sensitivity, and release controls in the audio
settings tab.
