Pull Request Overview

This PR improves the integration test reliability by making tests fail fast when the binary is missing and ensuring code quality checks pass before expensive API calls. The changes focus on preventing wasted resources and providing clearer failure feedback.

• Changes binary name from test-specific to production binary name
• Converts binary missing condition from skip to fatal error for faster feedback
• Updates test prompts from "pain" to "bread" while maintaining French translation validation
• Adds check prerequisite to integration target to validate code quality first
