"""Inject co-op branding + a per-build marker into the built index.html.

Non-fatal by design: if the file is missing or upstream changes shape, we
exit 0 so a cosmetic patch can never break a version bump.

The x-coop-build marker makes index.html unique per build, which changes the
service worker's precache revision — otherwise stale clients keep running the
old cached app shell (the "my changes never deploy" class of bug).
