feat: add repository_dispatch event support

- Add new progress MCP server for reporting task status via API
- Support repository_dispatch events with task description and progress endpoint
- Introduce isDispatch flag to unify dispatch event handling
- Make GitHub data optional for dispatch events without issues/PRs
- Update prompt generation with dispatch-specific instructions

Enables triggering Claude via repository_dispatch with:
{
  "event_type": "claude_task",
  "client_payload": {
    "description": "Task description",
    "progress_endpoint": "https://api.example.com/progress"
  }
}
