Subject: [PATCH] fix(mobile): update Node.js minimum requirement to 20.19.4

metro-config@0.83.3 uses Array.prototype.toReversed() which was added
in Node.js 20.0.0. The README incorrectly stated "Node.js 18+" causing
users to run `npx expo start` with Node 18 and hit:
  TypeError: configs.toReversed is not a function

- Update README.md to say "Node.js 20.19.4+" with nvm hint
- Update package.json engines from >=20.16.0 to >=20.19.4 to match
  metro-config's exact minimum (as declared in package-lock.json)
