Add auto-detection of project technology stack at REPL startup to prevent COCO from suggesting incompatible technologies. Features: - Detect language/runtime (Node.js, Java, Python, Go, Rust) - Extract dependencies from package.json, pom.xml, build.gradle, etc. - Infer frameworks (Spring Boot, React, FastAPI) from dependencies - Detect package manager, build tools, and testing frameworks - Enrich LLM system prompt with stack context - Prevent mismatched technology suggestions Added: - Stack detector service (src/cli/repl/context/stack-detector.ts) - CommandHeartbeat utility for future streaming feature - projectContext field in ReplSession type - Stack info in system prompt formatting Changed: - REPL startup now detects and stores stack context - System prompt enriched with technology stack information This prevents COCO from suggesting npm packages in Java projects and vice versa, significantly improving user experience.
