Add unit tests for skill capabilities, skill planner, and UV setup

- Implement tests for random ID generation, ensuring preference for crypto.randomUUID.
- Create tests for runtime context capabilities, validating the injection of enabled skill capabilities.
- Add tests for skill capability parsing, including classification and command example extraction.
- Introduce tests for the skill planner, verifying tool call planning based on user requests and attachment requirements.
- Establish tests for UV setup, ensuring proper handling of Python installation scenarios and environment checks.
