- Add aliases 'issue.comment' and 'issue_comment' to GITEA_OPERATION_ALIASES so short names normalize to gitea.issue.comment
- Grant 'issue.comment' (and short) in v2 example profiles for example-author and example-reviewer
- Grant in gitea-mcp.example.json mdcps-reviewer
- Update docs example profiles
- Add test coverage for new aliases and normalization
This enables gitea_create_issue_comment and list for profiles that include it, while preserving fail-closed for others and separation of duties (issue.comment does not imply pr.review etc).
Closes#137
