vad-web's own dependency was resolved to ort@1.24.3 (nested in its
node_modules), which only has threaded WASM requiring a .mjs dynamic
import that Vite fails to serve correctly. Pin ort to 1.18.0 via yarn
resolutions so all packages share the same copy with ort-wasm-simd.wasm
(non-threaded SIMD). Also remove the now-unnecessary COOP/COEP headers.

ort 1.19+ dropped non-threaded WASM binaries and replaced them with a
threaded .mjs loader that Vite's dev server fails to serve correctly
(wrong MIME type / transform interception). ort 1.18 ships ort-wasm-simd.wasm
which works with numThreads=1 and needs no .mjs dynamic import.

The threaded ORT WASM requires ort-wasm-simd-threaded.mjs to be served
alongside the .wasm files, and needs SharedArrayBuffer (COOP/COEP headers).
Add the .mjs to the static copy targets, add the required headers to the
Vite dev server, and set ort.env.wasm.numThreads=1 as a single-threaded
fallback that avoids the SharedArrayBuffer requirement entirely.

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.
