v1.1.0

Discourse Username Mapping

• Added GitHub → Discourse username mapping via owner/.github/discourse.yml (#3)
• Added optional github-token input for reading that mapping file

Behavior

• discourse-author-username still takes priority when set
• If omitted, action tries mapping from .github/discourse.yml
• If no mapping is found (or file is unavailable), falls back to system

Compatibility

• Backward compatible
