Subject: [PATCH] build(packages): emit ESM type marker, drop source export
 condition

- Add scripts/write-esm-package-json.js to write dist/esm/package.json
  with {"type":"module"} as a postbuild step. Required so bundlers
  (webpack, esbuild, vite, rollup) and older Node parse the ESM build
  as modules rather than CJS.
- Drop "source": "./src/index.ts" from each package's exports map.
  Source files are not shipped in dist/, so this condition pointed at
  nothing in the published tarball.
