# Copies the Matrix adapter in from the `channels` branch; appends the
# self-registration import; installs the pinned @beeper/chat-adapter-matrix
# package; patches the adapter's published dist so its matrix-js-sdk/lib
# imports carry .js extensions (required under Node 22 strict ESM); builds.
# All steps are safe to re-run — re-run this script after any pnpm install
# that touches the adapter.
