Replace 'as any' type assertions with proper TypeScript interfaces for improved type safety in Phase 8 integration tests.
Changes:
- Created response-types.ts with comprehensive interfaces for all response types
- Updated health-check.test.ts to use HealthCheckResponse interface
- Updated list-tools.test.ts to use ListToolsResponse interface
- Updated diagnostic.test.ts to use DiagnosticResponse interface
- Added null-safety checks for optional fields (data.debug)
- Used non-null assertions (!) for values verified with expect().toBeDefined()
- Removed unnecessary 'as any' casts throughout test files
Benefits:
- Better type safety and IDE autocomplete
- Catches potential type mismatches at compile time
- More maintainable and self-documenting code
- Consistent with code review recommendation
All 19 tests still passing with full type safety.
