fix: correct GitHub username tagging in release changelog (#112)

- Add GH_TOKEN environment variable for gh api calls
- Try both author.login and committer.login from GitHub API
- Add fallback mapping for known git authors (Gray Zhang -> @graycreate)
- This ensures releases show @graycreate instead of @gray

Author: graycreate
