There were two issues: the webpacker gem version was out-of-date with the @rails/webpacker NPM package and the config/webpacker.yml was missing the critical option to enable auto-refresh for webpack 5 (with which Webpacker 6 integrates).
Note: the beta Webpacker releases are more recent, but Bundler treats the pre release as the primary release. In this case, you want the beta release which has the fixes you need.
