.SYNOPSIS
    kimi-webbridge bootstrap installer (Windows).

.DESCRIPTION
    Detects platform (windows-amd64), downloads the daemon binary,
    starts the daemon, and installs skills into detected AI-agent runtimes.
    Windows counterpart to install.sh — the bash version is the source of
    truth; flags/env vars/prompts here mirror it with PowerShell-native style.
