8bit why: Dramatically improve performance when checking status of many repositories what: - Add StatusCheckConfig dataclass for configuration options - Implement StatusProgressPrinter for live TTY progress display - Create _check_repos_status_async() using asyncio.to_thread() pattern - Modify status_repos() to support both concurrent and sequential modes - Add --no-concurrent/--sequential flag to disable concurrency - Add --max-concurrent N flag to limit concurrent operations - Default concurrency: max(1, min(32, (os.cpu_count() or 4) * 2)) - Include duration_ms in summary when using concurrent mode - Show live progress: "Progress: 5/10 ✓:3 ✗:2" for TTY output - Preserve backward compatibility with sequential fallback refs: Follows same asyncio pattern as vcspull sync --dry-run
