refactor: remove ChromaDB references and replace with Qdrant

[jordanpartridge]

Summary

• Remove ChromaDB service from docker-compose.yml
• Add Qdrant service with proper configuration (ports 6333/6334, health checks)
• Update Makefile to reference Qdrant instead of ChromaDB
• Remove ChromaDB test from AppServiceProviderTest
• Add synapse-sentinel/gate badge to README

Breaking Changes

• Docker compose now uses Qdrant instead of ChromaDB
• Port mapping: Qdrant on 6333/6334 (was ChromaDB on 8000)
• Embedding server now depends on qdrant service

Context

ChromaDB was legacy dependency. Qdrant provides:

• Better Rust-based performance
• Production reliability
• Consistent with existing codebase architecture

Testing

• ✅ AppServiceProvider tests pass
• ✅ Docker compose configuration validated
• ✅ Makefile updated with correct health checks

All ChromaDB references removed while maintaining full functionality with Qdrant.

Summary by CodeRabbit

• Updates
  • Vector database service now uses Qdrant, accessible on port 6333 instead of port 8000
  • Updated startup messages, help text, and health check endpoints to reflect the new service
  • Updated Docker configuration and storage volumes for the new database backend

📝 Walkthrough

Walkthrough

The project migrates from ChromaDB to Qdrant for vector database management. Updates span the Makefile (help text, health checks, startup messages now reference Qdrant with endpoint http://localhost:6333), docker-compose.yml (service replacement with new ports and configuration), and test removal of ChromaDB-specific registration logic.

Changes

Cohort / File(s)	Summary
Infrastructure Configuration Makefile, docker-compose.yml	Replaced all ChromaDB references with Qdrant. Makefile updates help text, startup messages, and health check endpoints (http://localhost:6333/collections). Docker Compose replaces chromadb service with qdrant, updating container image, ports (6333:6333, 6334:6334), volumes (qdrant_storage), and environment variables (QDRANT__SERVICE__HTTP_PORT, QDRANT__SERVICE__GRPC_PORT).
Testing tests/Feature/AppServiceProviderTest.php	Removed test case verifying EmbeddingService registration when embedding provider is chromadb; chromadb-specific test assertion deleted.

Poem

🐰 Hopping forward, old paths fade away,
Qdrant arrives to save the day!
From port 8000 to 6333 we spring,
Vector knowledge finds new wing. 🚀
