Root cause: manifest-based Dockerfile created the home directory and
chowned only the home root. Files/directories copied from /etc/skel by
useradd -m (or created later by root) remained root-owned, so apps like
ranger failed when writing to ~/.config.
Changes:
- manifest_compiler.py: recursive chown of the home directory after
useradd so /etc/skel contents are owned by the container user
- Pre-create .config, .local/share, .cache and chown them to the user
so first-run apps have writable directories immediately
- Add unit test verifying the Dockerfile emits the expected user/home
setup and config directory creation
Quality gates: py_compile all backend files pass, test file compiles,
tsc --noEmit pass, npm run build pass, 82/82 web tests pass
Note: pytest not available in this shell; backend unit test was not
executed but follows existing project conventions.
