Subject: [PATCH 1/2] perf: swap ONNX Runtime JSEP WASM for CPU-only variant

Replace the 21MB JSEP WASM (includes unused WebGPU/WebNN support) with
the 11MB CPU-only variant via a Vite plugin. The transcription worker
uses device: 'wasm' exclusively so GPU backends are never initialized.

Build output drops from 25MB to 15MB.
