fix(og-image): bump to 6.3.7, clean config

6.3.7 root-fixes the hash propagation bug: options._hash is now set on
the original payload (not just the local copy), so the prerender plugin
stores hashes and OG image prerender succeeds without orphans.

Also fixes orphan cleanup (route.contents cleared for downstream hooks)
so module ordering (og-image before html-validator) prevents long-title
errors without needing the rule disabled.

No workarounds remain: no nitro.prerender.ignore, no html-validator
patch, no long-title: off.
