Issue Summary
README step 5 ("Set up Node") tells contributors to run nvm use, but the repo has no .nvmrc, so the command fails. The file (containing 20) was removed in #24002 (eslint 9 upgrade), apparently by accident, and was not restored by the Node 22 upgrade in #30416. Nothing else in the repo declares a Node version either: package.json engines lists only npm and yarn.
Steps to Reproduce
- Clone the repo.
- Follow README "Development Setup" to step 5.
- Run
nvm use.
Actual Results
$ nvm use
No version provided and no .nvmrc file found
Expected Results
nvm use switches to the project's Node version (22, per the Dockerfiles and CI workflows).
Suggested fix: re-add .nvmrc with 22, and optionally add "node": ">=22" to engines in package.json. Happy to open a PR.
