Subject: [PATCH] chore: untrack the .build-wt-028a5dca build worktree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It was committed as a gitlink (mode 160000) with no .gitmodules entry, so every
CI checkout's cleanup step ended with "No url found for submodule path
'.build-wt-028a5dca'" and a git exit-128 warning, and `git submodule` commands
failed in fresh clones. The worktree itself is removed locally; commit 028a5dca
stays reachable from this branch, so no history is affected.

Ignore the pattern so a throwaway build worktree cannot be committed again, and
add it to paths-ignore since such a directory can never change the binaries —
that also keeps this removal from triggering a pointless full rebuild.
