feat(api): improve cache handling and add API tests

Changes cache mode from BYPASS to WRITE_ONLY when cache is disabled to ensure
results are still cached for future use. Also adds error handling for non-JSON
LLM responses and comprehensive API test suite.

- Changes default cache fallback from BYPASS to WRITE_ONLY
- Adds error handling for LLM JSON parsing
- Introduces new test suite for API endpoints
