.DESCRIPTION
    Installs Ring skills to Claude Code, Codex, Factory AI, Cursor, Cline, and/or OpenCode.
    Multi-platform installer wrapper for the Python-based Ring installer.

.NOTES
    Requires: PowerShell 5.1 or later, Python 3.x
    Execution Policy: This script requires RemoteSigned or Bypass execution policy.

    Set execution policy:
        Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

    Or run with bypass:
        powershell -ExecutionPolicy Bypass -File install-ring.ps1

.EXAMPLE
    .\install-ring.ps1
    Interactive installation with platform selection

.EXAMPLE
    .\install-ring.ps1 install --platforms claude
    Direct installation to Claude Code

.EXAMPLE
    .\install-ring.ps1 update
    Update existing installation
