Subject: [PATCH 08/14] chore: replace fs-extra with native Node.js fs (#510)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* chore: replace fs-extra with native Node.js fs

Replace fs-extra with native Node.js fs APIs (node:fs/promises,
node:fs). All replacements are available on the supported Node >= 18:

- fs.pathExists() → fs.access() with boolean resolution
- fs.outputFile() → fs.mkdir({ recursive: true }) + fs.writeFile()
- fs.copy() → fs.copyFile() (glob ensures file-only results)
- fs.emptyDir() → fs.rm({ recursive, force }) + fs.mkdir({ recursive })
- fs.remove() → fs.rm({ recursive, force })
- fs.createReadStream() → named import from node:fs

This removes 1 runtime dependency (fs-extra + 3 transitive deps).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: convert env helper to async/await per review feedback
