# When opened from a git worktree, .git is a file whose `gitdir:` line points
# at the main repo's .git/worktrees/<branch>. That host path is not visible
# inside the dev container by default, so git commands inside the container
# fail with "fatal: not a git repository". Resolve the common git dir on the
# host and write it to .devcontainer/.env; docker-compose.yml bind-mounts it
# at the same path inside the container so the gitdir reference resolves.
