Remote Control: session label shows wrong GitHub repo (unrelated git repo from previous session)

Bug Description

When using Remote Control, the Claude mobile app displays an incorrect GitHub repository name as the session subtitle — showing a repo that is unrelated to the current working directory.

Steps to Reproduce

1. Start Claude Code from a workspace directory (e.g. ~/Ai agents/Claude Code/) that has no GitHub remote
2. Enable Remote Control (/config → Enable Remote Control for all sessions = true)
3. Connect from the Claude mobile app
4. Observe the session subtitle shows a previously-used GitHub repo (e.g. starcasttech/wordpress-project) instead of the current working directory

Expected Behavior

The session label should reflect the current working directory or show no repo if there is no GitHub remote associated with it.

Actual Behavior

The mobile app shows starcasttech/wordpress-project as the session subtitle even though Claude Code is running from a completely different directory with no relation to that repo.

Environment

• OS: Fedora Linux 43 (Wayland)
• Claude Code: latest (native install)
• Remote Control: auto-start enabled via /config
• Claude mobile app: Android

Workaround

User has to manually run /rename each session to override the incorrect label.
