Dev / Build: Prepare model according to https://github.com/praeclarum/transformers-js yarn yarn dev | yarn build

Test: Vitest: yarn test Chromium dev test: yarn dev and open the corresponding entry, then check the console. Don't use firefox

Test in downstream: test cases are exposed as browser_tests and can be called in downstream.

Misc: Lock-in onnxruntime-web for model opset. Test model first if you want to use a newer runtime ver.

The build warning can be ignored: Unable to determine content-length from response headers. Will expand buffer when needed. https://github.com/xenova/transformers.js/blob/aceab9bf3d1be9dadf6601b8f775e519376258e3/src/utils/hub.js#L547 不太需要管 https://github.com/xenova/transformers.js/blob/aceab9bf3d1be9dadf6601b8f775e519376258e3/src/utils/hub.js#L476-L482

transforming (110) node_modules/onnxruntime-web/lib/onnxjs/backends/webgl/ops/im2col.js'worker-loader?inline=no-fallback!./proxy-worker/main' is imported by worker-loader?inline=no-fallback!./proxy-worker/main?commonjs-external, but could not be resolved – treating it as an external dependency

As we are not using the ONNXRT built-in proxy feature (see here)
