Fixes issue #641 where users were getting banned due to rapid successive
Claude runs triggered by the synchronize event.
Changes:
- Add checkHumanActor call to agent mode's prepare() method to reject
bot-triggered workflows unless explicitly allowed via allowed_bots
- Update checkHumanActor to accept GitHubContext (union type) instead
of just ParsedGitHubContext
- Add tests for bot rejection/allowance in agent mode
