refactor: implement discriminated unions for GitHub contexts

Split ParsedGitHubContext into entity-specific and automation contexts: - ParsedGitHubContext: For entity events (issues/PRs) with required entityNumber and isPR - AutomationContext: For workflow_dispatch/schedule events without entity fields - GitHubContext: Union type for all contexts This eliminates ~20 null checks throughout the codebase and provides better type safety. Entity-specific code paths are now guaranteed to have the required fields. Co-Authored-By: Claude <noreply@anthropic.com>
