Show GitHub repository name in CLI status line

Feature Request

Current behavior:
The Claude Code CLI status line shows the current branch and working directory, but not the GitHub repository name.

Desired behavior:
Show the GitHub repository name (e.g., org/repo-name) in the status line alongside the branch name. This would be especially helpful when working across multiple repositories in different terminal sessions.

Example:
Currently: branch: main
Desired: Intermega/PortalMega365 · branch: main (or similar format)

Why:
When working with multiple repos, it's easy to lose track of which repository you're in. Having the repo name visible at a glance in the status line would improve context awareness.
