Track the Claude Code statusline script

Track the Claude Code statusline script 4cef4ec dropped the statusLine block from .claude/settings.json because it pointed at a script that was neither present nor tracked. The statusline that replaced it lived in an untracked clone under ~/.claude/statusline, so it existed on this machine only. Vendors statusline.sh from daniel3303/ClaudeCodeStatusLine at 5da9695 and links it to ~/.claude/statusline.sh. settings.json stays unmanaged, so each machine still needs: "statusLine": { "type": "command", "command": "bash ~/.claude/statusline.sh" }
