[BUG] Claude remote control complains about missing github access, despite us being a bitbucket org

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Navigating to https://claude.ai/code brings me to https://claude.ai/code/onboarding which insists on "GitHub access is required for Claude Code on the web. Please contact an organization owner."

Why? I want to remote control existing sessions and the planned work has nothing linking to GitHub

### What Should Happen?

https://claude.ai/code should let me remote control sessions

### Error Messages/Logs

```shell

```

### Steps to Reproduce

Navigating to https://claude.ai/code

You get the error.

### Claude Model

None

### Is this a regression?

Yes, this worked in a previous version

### Last Working Version

_No response_

### Claude Code Version

2.1.270

### Platform

Anthropic API

### Operating System

macOS

### Terminal/Shell

Terminal.app (macOS)

### Additional Information

_No response_

Start by reproducing the redirect from https://claude.ai/code to /onboarding with Claude Code 2.1.270 on macOS, then trace the onboarding check that requires GitHub access for an organization using Bitbucket. Done means remote control of existing sessions works without an unnecessary GitHub requirement.
