- Created comprehensive test suite for cache.ts covering:
- set() and get() operations with various data types
- TTL expiration logic (default, custom, and edge cases)
- has() method for checking key existence
- delete() method for removing individual keys
- clear() method for removing all keys
- Expiration boundary testing
- Different TTL values for different items
- TTL reset when items are overwritten
- Fixed vitest.config.ts to include src/utils/** tests
- Fixed tsconfig.json to include src/utils/** files
- Used vi.useFakeTimers() for deterministic time-based testing
- All tests properly isolated with beforeEach/afterEach hooks
