Research findings:
- Coolify provides SOURCE_COMMIT environment variable with git commit hash
- Must enable "Include Source Commit in Build" in Coolify General settings
- Disabled by default to preserve Docker build cache
- Coolify automatically passes SOURCE_COMMIT as build arg
Changes:
1. Dockerfile: Use SOURCE_COMMIT build arg instead of GIT_COMMIT
2. Dockerfile: Remove git installation and detection logic
3. Dockerfile: Extract first 7 chars of SOURCE_COMMIT for short hash
4. docker-compose.yml: Pass SOURCE_COMMIT instead of GIT_COMMIT
5. docker-compose.yml: Remove GIT_COMMIT from env (set in Dockerfile)
6. README: Add instructions to enable "Include Source Commit in Build"
7. README: Update version tracking documentation
How it works:
- Coolify passes SOURCE_COMMIT to docker build
- Dockerfile takes first 7 characters: ${SOURCE_COMMIT:0:7}
- Sets as GIT_COMMIT env var for runtime
- Health endpoint returns the short commit ID
Note: Returns "unknown" if SOURCE_COMMIT tracking is not enabled.
