Subject: [PATCH] fix: support Apple Silicon in dev-bundle fast path

getHostArch() in dev-bundle.js always returned "os.osx.x86_64" on
macOS, regardless of the actual architecture. On Apple Silicon machines,
the meteor-tool is installed under mt-os.osx.arm64, so the dev_bundle
directory lookup failed and the fast path for `meteor node` / `meteor
npm` was never used.

Check process.arch to return the correct architecture string on
Apple Silicon Macs.
