:: Qoder CLI Installer for Windows CMD
:: Usage: curl -fsSL https://qoder-ide.oss-accelerate.aliyuncs.com/qodercli/install.cmd -o install.cmd && install.cmd && del install.cmd
::
:: Responsibilities (script layer):
::   - Manifest fetch, download, SHA256 verification, extraction
:: Post-extraction, delegates to binary's `install` subcommand for:
::   - Versioned placement, entry-point, PATH config, marker, verification, telemetry
