refactor: convert all packages to ESM with named exports (#224)

- Add `"type": "module"` and `"exports"` field to all package.json files
- Convert all `require()`/`module.exports` to `import`/`export`
- Replace all `export default` with named exports across source, types, and tests
- Switch inter-workspace dependencies to `workspace:^` protocol
- Remove `dependenciesMeta`/`injected` self-reference pattern (caused infinite prepublishOnly loop)
- Update `pnpm-workspace.yaml` to exclude `**/node_modules_link/**`
- Fix `fs-extra` import in rename-overwrite (CJS package needs default import)
- Update which-pm-runs test fixtures to ESM
