--target bundler generates static WASM ESM imports that only work
through a bundler (vite-plugin-wasm). --target web generates fetch-based
WASM loading via import.meta.url which browsers handle natively.
- Change wasm-pack build target from bundler to web
- Call wasmModule.default() (init) after import in maybeLoadWasm
- Restore rollupOptions.external so WASM stays a separate fetch
- Removes the need for vite-plugin-wasm in any consumer
