Subject: Warn if `npm run start` is out of date. (#20)

* Adding some wiring to allow the Ink app to warn if there are local development changes that haven't been captured in the recent build of the Gemini CLI.

* Adding a new useAppEffects.ts file that wores some useEffect handlers in.

* Updating package-lock.json to resolve `npm ci` issues.

* Updating package-lock.json and package.json to resolve `npm ci` issues.
