feat: Achieve 100% test coverage (58/58 tests passing)

- Fix time format validation regex to require leading zeros
- Fix content handler validation with proper async/await
- Resolve Jest configuration issues with dist directory exclusion
- All test suites now passing: advanced-scenarios, enterprise-scenarios, daily-notification, edge-cases
- Complete validation system working correctly for time, timezone, content handlers
- Test suite stability confirmed with multiple runs
