Subject: [PATCH] Fix PR labeler for branches without merge base
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add fallback logic when git diff fails due to no merge base between branches. This handles cases where the branch history has diverged significantly.
