fix(types): resolve import path and type issues after consolidation

- Added GoogleFontItem type alias for backward compatibility
- Updated normalize.ts to properly type Record<string, string> values
- Fixed import paths in Font index.ts (added subdirectory paths)
- Removed unused Readable import from store
- Removed type exports from normalize and API index files
- Updated stores index.ts to import types from parent types.ts
- All tests passing (129 tests)

All imports now use centralized types from model/types.ts:
- API clients re-export types for backward compatibility
- Normalize module imports types and exports functions
- Store module imports types and exports factory
- Main index.ts exports all types from model/types.ts
