fix --limit alias to properly map to --pr-limit

Changes:
- Add aliases: ['limit'] to prLimit flag definition
- Remove separate limit flag from hiddenFlags that was causing conflicts
- Add comprehensive tests for --limit alias functionality

The --limit flag now properly functions as a hidden alias for --pr-limit,
resolving the issue identified in PR #960 discussion.
