	# only reaches for it when globalThis.Bun is defined. This runs under
	# Node.js, so node-pty, which is built here from its own sources, is what
	# gets loaded; even under bun the import is wrapped in a try and falls
	# back to it. Drop it from the dependencies as well, otherwise "npm
	# prune" trips over the gap.
