Subject: [PATCH] fix: use one-shot flag for pagefind instead of incremental
 guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The --incremental CLI flag sets incremental=true in eleventy.after even
for the watcher's first full build, so pagefind was never running when
the initial build was OOM-killed. Replace the incremental guard with a
pagefindDone boolean that runs pagefind exactly once per process lifetime
— whichever build completes first (initial or watcher) gets indexed.
