- Add robust unit tests for base64Url in tests/serve.test.js
- Wrap server.listen in require.main === module to prevent port collisions during testing
- Export base64Url conditionally for testing

Subject: [PATCH 2/2] fix: resolve Bun.build failure caused by missing wasm
 files

- Updated `build.mjs` to use recursive `cp` instead of iterating and checking with `readdir` directly, which fixes `EISDIR` errors
- Marked generated WASM JS and binary files as external in the Bun builder configuration to prevent CI resolution errors when the artifacts aren't built
- Verified that `serve.test.js` remains intact and `base64Url` runs accurately.
