Features:
- AsyncQdrantClient for non-blocking Qdrant operations
- Singleton pattern for QdrantService
- Monthly full curation (day 1 at 03:00)
- Configurable UID/GID for Docker
- Timezone support via TZ env var
- Configurable log directory (VERA_LOG_DIR)
- Volume mounts for config/, prompts/, logs/
- Standard Docker format with .env file

Fixes:
