dockerimg: add only git objects to docker image

Instead of copying the entire working directory
(including uncommitted changes, hooks, and config files),
create a bare git repository and use git clone --reference.

This approach:
- Avoids copying uncommitted changes, hooks, and local config files
- Works correctly with git worktrees and submodules
- Reduces Docker image size substantially
- Maintains all git history and functionality
