Subject: [PATCH] fix(ui): stop treating git worktrees and submodules as repos
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

.git as a file (worktrees, submodules) isn't a standalone repo — the
scanner was flooding the import list with worktree entries alongside
their real repo.
