In a linked worktree `.git` is a file naming that worktree's gitdir, not a
directory, so reading `PROJECT_ROOT/.git/config` raised NotADirectoryError.
`_git_config` catches OSError and returns an empty mapping, which left
`_owner_and_repository` without a remote and `mirror_image` returning None
for every image.

The consequence was silent: every probe addressed the upstream registry
directly, so all image work done from a worktree bypassed the GHCR mirror
and hit Docker Hub instead. The rate limits and handshake timeouts that
showed up as flaky `test-external` runs came from there.

`_config_path` follows the indirection: a `.git` directory keeps its own
config, a `.git` file is read for its gitdir and that dir's `commondir`
points at the shared config. Reads go through utils.cache.files, which the
uncached-read lint requires under utils/.
