fix: resolve all remaining test failures and improve test reliability

- Fix clear-subtasks test by implementing deep copy of mock data to prevent mutation issues between tests - Fix add-task test by uncommenting and properly configuring generateTaskFiles call with correct parameters - Fix analyze-task-complexity tests by properly mocking fs.writeFileSync with shared mock function - Update test expectations to match actual function signatures and data structures - Improve mock setup consistency across all test suites - Ensure all tests now pass (329 total: 318 passed, 11 skipped, 0 failed)
