-The install script downloads a standalone `**grok**` binary for your platform, places it in `**~/.grok/bin**`, and records install metadata so `**grok update**` and `**grok uninstall**` work automatically.

-Supported targets: macOS (Apple Silicon), Linux x64, and Windows x64. Intel Macs run the ARM binary via Rosetta 2.
-
-**Installer flags:**
