Addresses several points of failure during the skill generation and validation lifecycle to prevent crashes and provide better error visibility. Additionally, it expands the capability of the `resources` field to accept local relative file paths in addition to URLs.
Key changes include:
- **Expanded Resource Support:** Updated `BaseSkillCommand` and `SkillParams` to allow the `resources` list to take both URLs and relative file paths, improving local testing and generation workflows.
- **Service Robustness:** Enhanced `GeminiService` and API interactions to gracefully handle errors, empty responses, and malformed JSON payloads.
- **Command Reliability:** Updated `GenerateSkillCommand` and `ValidateSkillCommand` to detect and gracefully log generic exceptions and empty content fetches instead of failing silently or crashing.
- **HTML/Markdown Parsing:** Broadened test coverage to cover conversions for tables, definition lists (dl/dt/dd), video sources, iframes, and details/summary HTML tags.
- **Comprehensive Testing:** Added unit tests across `generate_skills_test.dart`, `validate_skills_test.dart`, and `gemini_service_test.dart` to explicitly cover invalid API responses, missing metadata fallbacks, and retry logic.
- **Documentation:** Updated `README.md` to reflect the refined parameters, new resource path capabilities, and handling logic.
