/**
* Resolve `import X from '*.wasm?binary'` imports to an inline Uint8Array.
*
* The `?binary` suffix is a build-time hint: at bundle time (esbuild) the WASM
* bytes are embedded as base64 and exported as a default Uint8Array, so no
* external vendor files are needed at runtime. In source / transpiled mode
* the dynamic import throws and the caller falls back to reading from
* node_modules via `require.resolve`.
