Closes the gap between Python and TypeScript SDK hook output types by
adding:
- `reason` field for explaining decisions
- `continue_` field for controlling execution flow
- `suppressOutput` field for hiding stdout
- `stopReason` field for stop explanations
- `decision` now supports both "approve" and "block" (not just "block")
- `AsyncHookJSONOutput` type for deferred hook execution
- Proper typing for `hookSpecificOutput` with discriminated unions
Also adds comprehensive examples and tests:
- New examples in hooks.py demonstrating all new fields
- Unit tests in test_tool_callbacks.py for new output types
- E2E tests in e2e-tests/test_hooks.py with real API calls
- CI integration in .github/workflows/test.yml
