Subject: [PATCH] Fix bind mount failure when ~/.gitconfig does not exist (#24)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Docker bind mounts require the source file to exist. Users without
~/.gitconfig (fresh machines, XDG-based config, system-only config)
hit a container start failure.

Add initializeCommand to create an empty ~/.gitconfig on the host
before the container starts. An empty gitconfig is valid and has no
side effects — git treats it as having no settings.
