Parent	#401

Description

The devcontainer Dockerfile build fails at step 30/30 with:

fatal: not a git repository (or any of the parent directories): .git

Root cause: .dockerignore excludes .git/ (line 11), so COPY . $APP_DIR never copies the .git directory into the image. However, Dockerfile line 234 runs git clean -xdf unconditionally, which requires a git repository to exist.

The git clean -xdf and rm -rf .git commands on lines 234-235 both assume .git is present, but the .dockerignore ensures it is not.

Subtasks

Make git clean -xdf and rm -rf .git conditional on .git directory existence
Verify the Docker build succeeds

Definition of Done

docker build completes successfully with .dockerignore excluding .git/
All nox quality gates pass
PR opened and CI green
