- Removed Homebrew tap installation (felixisaac/homebrew-tap doesn't exist)
- Removed Scoop bucket installation (felixisaac/scoop-bucket doesn't exist)
- Added working curl-based installation for Linux/macOS
- Added PowerShell one-liner for Windows
- Removed brews and scoops sections from .goreleaser.yaml
