Same bug Joost fixed on specification.email (PR #3, commit 32d0006), present here too: the manifest's mdUrl was absolute (site.url), so on Cloudflare Pages preview deployments get_topic fetched the production Markdown instead of the preview's — blocked by this site's connect-src 'self' CSP.

Makes mdUrl root-relative; the canonical url stays absolute. Adds the same per-origin regression test (preview.example.pages.dev + local dev) to scripts/test-webmcp.mjs.

Verified: full build + check-integrity pass, test:webmcp 7/7, eslint clean (0 errors), Prettier clean.
