An MCP client can sign in through AuthKit to a brand-new account with no Executor Cloud organization (new sign-ups belong to Executor v2). Every MCP request then got 403 "No organization in session — log in via the web app first", which sends the person back to a v1 web app they should not be using. Clients kept retrying.

When neither the token nor the URL names an organization, the 403 now says Executor has moved and to connect https://mcp.executor.sh/mcp. It also covers the rare account that joined a v1 organization after signing in: reconnect and sign in again to choose it.

The status stays 403 with no WWW-Authenticate challenge. A 401 or an insufficient_scope challenge would make the client sign in again, which lands on the same account. MCP SDK clients surface the body of a plain 403 as the error text. Nothing else changes: pinned org URLs, members of an organization, forwarding for moved orgs, and the revoked-membership answer.

Tests are in #2495.
