Windows x64 binary published

Minor Changes

• c80aacb: feat(cli): publish a Windows x64 binary. npm install -g @buildinternet/releases now works on Windows; the dispatcher resolves releases.exe from the new @buildinternet/releases-windows-x64 platform package. Homebrew remains macOS/Linux-only. windows-arm64 is intentionally not shipped — open an issue if you need it.
