Subject: [PATCH] refactor: remove ChromaDB references and replace with Qdrant

- Remove ChromaDB service from docker-compose.yml
- Add Qdrant service with proper configuration
- Update Makefile to reference Qdrant instead of ChromaDB
- Remove ChromaDB test from AppServiceProviderTest
- Add synapse-sentinel/gate badge to README

BREAKING CHANGE: Docker compose now uses Qdrant instead of ChromaDB
