问题描述 · Description

Initially, around 2 days into using the Start Plan 5 day quota, all of the sudden, ZCode decides to work at all with my Z.ai account as the provider. Whenever I log into ZCode with my Z.ai account, It never automatically applies my 5 day quota, but instead, the chat shows that there is "No Model Available, Upgrade or set a custom model"

In the model settings page, It shows that "Z.ai" as the provider, is disabled, and there is no option to select the "Start Plan"

复现步骤 · Steps to reproduce

1. Open ZCode
2. When it asks to "Connect your account to start using ZCode", select "Connect to Z.ai"
3. Log into Z.ai with an account that is eligible for the quota (An account that has not used the quota yet / an account that has part of their 5 day quota remaining)
4. Try and send a message / See whether or not ZCode allows you to send a message with either GLM Model.

期望表现 · Expected behavior

Should allow you to send a message / use the models with the Start Plan

实际表现 · Actual behavior

Actually does not allow you to use the models, and the Start plan quota is not activated

No repository file, test, or entry point is named in the report. Start by reproducing the Z.ai connection flow on Windows 11 with an eligible account, then trace how provider status and Start Plan entitlement are applied; done means GLM models are available and messages can be sent under the remaining quota.
