  - Prevent malicious SQL through filter parameters

- Add input sanitization for OpenAI API calls
  - Sanitize template names and descriptions before sending to API
  - Remove control characters and prompt injection patterns
  - Limit input length to prevent token abuse

- Lower temperature to 0.3 for consistent structured outputs

- Add comprehensive test coverage
  - 100+ new tests for metadata functionality
  - Security-focused tests for SQL injection prevention
  - Integration tests with real database operations
