Rebuild dist/ for the Node 24 ESM bundle

Regenerate the ncc-bundled `dist/index.js` and its source map to
reflect all the preceding source changes. The bundle is now an ESM
entry point (importing `./sourcemap-register.cjs` and using
`createRequire` for any remaining CJS interop) rather than the
previous CommonJS bundle, matching the `"type": "module"` declared
in `dist/package.json`.
