Failing MCP calls now share one login retry instead of firing several at once.
What's wrong with this entry?
Anonymous. No account, no email.
What
The MCP client now tracks whether a re-authentication is already running for each server, and both the tool-call and connect retry paths check it before treating a closed connection as grounds for another attempt. Several calls failing together now share one OAuth re-auth.
Evidence
reauthInFlight = new Map();
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
