- utils.py: support OMBRE_DEHYDRATION_BASE_URL and OMBRE_EMBEDDING_BASE_URL
so Gemini/non-DeepSeek users can configure without mounting a custom config
- docker-compose.user.yml: pass all 4 model/url env vars from .env;
add commented Gemini example + optional config.yaml mount hint
- ENV_VARS.md: document OMBRE_DEHYDRATION_BASE_URL and OMBRE_EMBEDDING_BASE_URL
- check_icloud_conflicts.py: scan bucket dir for iCloud conflict artefacts
and duplicate bucket IDs (report-only, no file modifications)
