* feat(mcp): allowlist Grok's connector callback and document the Grok path
Grok custom connectors self-register through /api/mcp-oauth/register with
redirect_uri https://grok.com/connectors-oauth-exchange-code/, which the
built-in allowlist rejected with invalid_redirect_uri before consent. Add
the callback as an exact-path BUILT_IN_PATTERNS entry (trailing slash
optional, no prefix) with provider 'grok', named "Grok (xAI)" on the
consent page. Tests: accept, foreign-host and other-path rejection,
provider mapping, and a register route test for the Grok DCR shape.
Surface Grok next to ChatGPT: a "Using Grok?" side door on the onboarding
Claude step (one side door open at a time, telemetry step grok), a Grok row
under "Other clients" in the API & MCP settings tab using ?client=grok, and
sv/en strings for both. Docs: mcp-server rule, ARCHITECTURE, README,
registry entry (install section), DECISIONS.

* fix(mcp): cite X Corp's published Grok callback, test the consent label
Review pass on #2158: the allowlist comment and DECISIONS entry claimed
xAI publishes no callback and the value came from a live observation; X
Corp lists https://grok.com/connectors-oauth-exchange-code/ as the "Grok
(web)" redirect URL at docs.x.com/x-ads-api/mcp, and grok.com serves the
path itself (slash form 308s to no-slash on the same origin). Reworded
both to cite that. Adds the consent-page test for "Grok (xAI)" next to
the ChatGPT one and a JSDoc on the onboarding side-door toggle.
