cverdict-mcp 0.1.3

Site address: https://cverdict.dev

BRAND.siteUrl moves to https://cverdict.dev, so feed and calendar links,
link-preview fallbacks, the MCP server's page links and its fallback data
base (from 0.1.3), the README, the docs, the issue form and the MCP
Registry entry (websiteUrl) all point to the new domain. On Vercel the
build and the link-preview function take the production domain from
VERCEL_PROJECT_PRODUCTION_URL, which is cverdict.dev now.

The Atom feeds' feed and entry IDs keep the first address through the
new BRAND.feedIdBase, so no feed reader sees an entry twice: a real run
against the live data branch gives the same IDs on the old host and
links on cverdict.dev. Tests pin feedIdBase and check that the IDs do
not move with siteUrl. cverdict-psi.vercel.app keeps serving the site,
which MCP 0.1.0 to 0.1.2 use as their fallback.
