What's Wrong?

Description:
When a session is started natively in the Claude Desktop app from a project directory (e.g. ~/my-project), it correctly appears grouped under a sidebar section named for that project.

However, when a claude remote-control session is started from a terminal in that same directory, it does not get grouped under that project's section — it instead appears under a generic "Other" section, even though both sessions are working in the identical folder.

What Should Happen?

Expected: The Remote Control session groups under the same project section as the native Desktop session, since it's rooted at the same working directory.

Actual: The Remote Control session appears under "Other" instead.

Steps to Reproduce

Open a session in Claude Desktop app rooted at a project directory (e.g. ~/my-project) — confirm it appears under a matching project section in the sidebar.
In a terminal, cd into that same directory and run claude remote-control.
View the resulting Remote Control session in the sidebar (Desktop app or claude.ai/code).
