test(ai): add comprehensive functionality tests

Add test coverage to ensure AI features are working
correctly and remain functional.

- Add RSpec tests for endpoint construction
- Add RSpec tests for environment context gathering
- Add RSpec tests for dual prompt modes
- Add RSpec tests for temperature configuration
- Add integration test script for manual validation
- Add simple functionality test for CI/verification

Tests verify base URL handling, context collection,
prompt modes, and all new AI strategy features.
