[BUG] Claude Code VS Code extension resolves account to API org instead of active Pro subscription

What's Wrong?

The Claude Code VS Code extension is authenticated via OAuth with the correct account, but resolves it to my API organization instead of my active Pro subscription. Every request fails instantly with "Credit balance is too low".

Account & Usage panel shows:

• Auth method: Claude AI
• Email: (matches my Pro subscription account)
• Organization: my individual API org
• Usage: "Usage tracking is only available for Claude AI subscribers"

Checked and ruled out:

• ANTHROPIC_API_KEY is not set (verified with echo, empty)
• No API key or apiKeyHelper in ~/.claude/settings.json or project settings
• No .env in the project
• VS Code fully restarted several times
• Pro subscription is active and works normally on claude.ai

Cannot work around it: the extension's Account & Usage panel has no sign-out control, so there is no way to force re-authentication from the UI.

Environment: macOS, VS Code, Claude Code extension.

What Should Happen?

The extension should resolve the account to the active Pro subscription and use subscription billing, as documented for Pro and Max subscribers. The Account & Usage panel should show subscription usage instead of "Usage tracking is only available for Claude AI subscribers".

Error Messages/Logs

Steps to Reproduce

1. Have a Claude Pro subscription active on an account that also has an individual API organization with zero credits.
2. Ensure ANTHROPIC_API_KEY is unset in the environment.
3. Open the Claude Code extension in VS Code and authenticate via OAuth with that account.
4. Send any prompt, however short.
5. The request fails immediately with "Credit balance is too low".
6. Open Account & Usage: Auth method is "Claude AI" with the correct email, but Organization resolves to the individual API org.
