fix: System font fallback and status bar improvements
Font Changes: - Use system fonts FIRST (SF Mono, Menlo, DejaVu Sans Mono) to avoid "Unable to load font" errors on fresh macOS/Linux installs - JetBrains Mono and Fira Code moved to END of fallback chain - Rust default: Menlo (macOS), DejaVu Sans Mono (Linux), Consolas (Windows) Status Bar (cx.lua): - Added Git branch indicator with dirty status (yellow dot) - Added "AI Ready" indicator in CX teal - Added current working directory on left - Added Ctrl+Space hint Key Bindings (cx.lua): - Ctrl+Space: AI panel (command palette) - Ctrl+Shift+F: Fix last error (sends "cx fix-last-error") - Ctrl+Shift+E: Explain output (sends "cx explain") - Cmd+D: Split horizontal, Cmd+Shift+D: Split vertical - Cmd+1-9: Switch tabs - Session persistence via unix domains Fixes the font error from: ERROR mux::connui > Configuration Error: Unable to load a font...
