Update a custom toolkitv3.1

PATCH
/api/v3.1/custom/toolkits/{slug}

Experimental: custom toolkit access control is in pilot and this contract may change. Updates a custom MCP toolkit owned by the project: its name, logo and API key input copy on the connect page (api_key_field). Omitted fields keep their current value. app_url, auth_schemes and who can use the toolkit (user_id) cannot be changed; delete and re-create the toolkit instead. Composio-managed toolkits and toolkits of other projects return 404.
