fix: threshold parameter validation in analyze-complexity

Change threshold parameter in analyze_project_complexity from union type to coerce.number with min/max validation. Fix Invalid type error that occurred with certain input formats. Add test implementation to avoid real API calls and proper tests for parameter validation.
