Show branch status in workspace name header

[ammario]

Filed by cmux AI assistant

Problem

The WorkspaceTitle in AIView.tsx (line 436) shows only {projectName} / {branch} with no git status indicators. Users cannot tell if their branch is behind/ahead, has uncommitted changes, conflicts, etc.

Solution

Add git status indicators to the workspace header:

• ↓N / ↑N - commits behind/ahead
• ● - dirty changes
• ⚠️ - conflicts

Example: cmux/main ↓2 ● (2 behind, dirty changes)

Implementation

• Component: src/components/AIView.tsx (WorkspaceTitle at line 436)
• Add git status check (debounced/cached for performance)
• Update on file changes, commits, fetch operations
• Consider using simple-git or native git calls via IPC
