Subject: [PATCH] fix: add production rewrite for /api/mcp to mcp.tempo.xyz

The Try the MCP server explorer POSTs to /api/mcp, which works in dev via
the vite proxy but 404s in production (falls through to the marketing app,
308 -> /api/mcp/ -> 404.html). Add a Vercel reverse-proxy rewrite mirroring
the dev proxy so the same-origin request reaches mcp.tempo.xyz (which omits
CORS headers on POST, so a direct browser call cannot work).
