Changelog and Version Management

No changelog or version changes detected. You can either update them manually or use a comment command to update them automatically on merge:

/pr_prepare release:<patch|minor|major> — bump version + update changelog
/pr_prepare changelog:add — changelog entry only (no version bump)

/pr_prepare release:patch
- Add the changelog entry here
  - (Additional details can be provided in multiple lines, respecting markdown formatting)

Omit the entry line to use the PR title. If multiple commands are posted, the last one wins.
