🤖 fix: use prebuilt node-pty to avoid build requirements

Replace node-pty with @homebridge/node-pty-prebuilt-multiarch which
includes prebuilt binaries for common platforms (Linux, macOS, Windows).

This allows mux to be installed on servers without requiring build tools
(python3, node-gyp, make, g++). The prebuilt package is API-compatible
with node-pty and works with both Node.js and Electron.

Fixes the error:
  node-pty [1/2] > Copying prebuilds to release folder...
  SKIPPED Prebuild directory does not exist
  /usr/bin/bash: line 1: node-gyp: command not found
  error: install script from "node-pty" exited with 127

_Generated with `mux`_
