refactor: extract CLI tool utilities and add cloud mode tests

Refactor CLI tool commands to eliminate code duplication and improve
testability by extracting shared utilities.

Changes:
- Create tool_utils.py with resolve_project() and run_async_tool()
- Refactor all 6 CLI tool commands to use new helpers
- Add project parameter to recent_activity for consistency
- Fix search_notes search_type logic bug (was overwriting itself)
- Add comprehensive unit tests for tool_utils
- Add cloud mode routing and auth tests

Benefits:
- 32% code reduction (342 → 234 lines in tool.py)
- Consistent error handling across all commands
- Better testability with extracted utilities
- Cloud mode functionality validated

Fixes #346
