 * RuFlo V3 Statusline Generator (Optimized)
 * Displays real-time V3 implementation progress and system status
 *
 * Usage: node statusline.cjs [--json] [--compact]
 *
 * Performance notes:
 * - Single git execSync call (combines branch + status + upstream)
 * - No recursive file reading (only stat/readdir, never read test contents)
 * - No ps aux calls (uses process.memoryUsage() + file-based metrics)
 * - Strict 2s timeout on all execSync calls
 * - Shared settings cache across functions
