chore: prune verified Vercel verification TXT records

[bosquejun]

🧹 Automated Vercel TXT cleanup

The subdomains below are attached and verified on Vercel — their
edge serves the site with no x-vercel-error — so the single-use
vc-domain-verify challenge is dead weight and has been removed
from their JSON files.

Merging this PR triggers the Sync workflow, which deletes the
now-orphaned _vercel TXT records from Cloudflare. Nothing has been
deleted from Cloudflare yet.
