Fix Windows shortcut updates and sign .node artifacts

- use `replace` when writing Windows mpv shortcuts and update tests
- include `*.node` files in SignPath Authenticode signing config
- document WinShell plugin sourcing in installer/build notes

Packaged macOS and Windows installs do not require Bun. Windows installer builds go through `electron-builder`; its bundled `app-builder-lib` NSIS templates already use the third-party `WinShell` plugin for shortcut AppUserModelID assignment, and the `WinShell.dll` binary is supplied by electron-builder's cached `nsis-resources` bundle, so `bun run build:win` does not need a separate repo-local plugin install step.
