fix(#1427): disable ChromaDB telemetry for sovereignty

ChromaDB enables anonymous telemetry by default, leaking usage
patterns to Chroma Inc. This violates local-first sovereignty.

Two layers of protection:
1. Set ANONYMIZED_TELEMETRY=false env var at import time
2. Pass Settings(anonymized_telemetry=False) to PersistentClient

Closes #1427
