Claude in Chrome: Team accounts show "requires a claude.ai subscription" error

Description

The Claude in Chrome extension shows "Claude in Chrome requires a claude.ai subscription" on every use, even when the user is authenticated with a valid Team account.

Steps to Reproduce

1. Log in to Claude Code with a Team (org) account via claude.ai auth
2. Install the Claude in Chrome Chrome extension
3. Attempt to use the extension

Expected Behavior

Team accounts should be recognized as valid subscriptions and the extension should work without error.

Actual Behavior

The extension repeatedly shows: "Claude in Chrome requires a claude.ai subscription"

Root Cause (suspected)

claude auth status returns subscriptionType: null for Team/org accounts:

{
  "loggedIn": true,
  "authMethod": "claude.ai",
  "apiProvider": "firstParty",
  "subscriptionType": null
}

The Chrome extension appears to check subscriptionType and rejects null, not recognizing that Team accounts are billed at the org level and do not have a personal subscriptionType set.

Environment

• OS: macOS
• Auth method: claude.ai (org/Team account)
• subscriptionType in auth status: null

Workaround

None currently. Users on Team accounts cannot use the Claude in Chrome integration.
