test: achieve 100% test pass rate following Guido's philosophy

- Remove all unconditional test skips
- Fix parameter mismatches in tool initialization
- Add comprehensive mocking for optional dependencies
- Implement property-based testing patterns
- Add robustness tests for edge cases
- Ensure thread safety for singleton patterns
- Test graceful degradation when dependencies missing
- Achieve 31/31 tests passing (100% pass rate)
