Sessions on the same machine are now automatically grouped by git repository (or working directory) in the sidebar.

What Changed

Previously, all sessions under a machine were listed flat — making it hard to tell which sessions belong to the same project. Now, sessions sharing the same gitRepo are visually grouped together with a collapsible header.

• Repo subgroup header — shows the repository name, a git icon, and a session count badge
• Branch info — each session now displays its gitBranch (e.g. main, master, worktree/feature) instead of repeating the machine name
• Collapse/expand — click the subgroup header to toggle visibility
• Single-session groups — if only one session exists for a repo, no extra header is shown

How Grouping Works

1. If the session reports a gitRepo, that value is used as the group key
2. If no git info is available, the last folder name from the session's working directory is used
3. Sessions are sorted within each group: online first, then alphabetical

Example

devload-macbook
  > sessioncast-myworkspace (3)
      sessioncast          main
      sessioncast-admin    main
      test-tmux            worktree/test-tmux
  > threadcast-myworkspace (2)
      threadcast-ws        master
      threadcast-admin     master

This makes it much easier to navigate when you have many sessions across multiple projects on the same machine.
