Depencency jenssegers/agent conflicts with Jetstream

The jenssegers/agent package hasn't been updated in 4 years and has a dependency conflict now with Laravel Jetstream.

- laravel/jetstream[v4.1.0, ..., v4.2.2] require mobiledetect/mobiledetectlib ^4.8 -> satisfiable by mobiledetect/mobiledetectlib[4.8.01, ..., 4.8.05].
- You can only install one version of a package, so only one of these can be installed: mobiledetect/mobiledetectlib[2.7.6, ..., 2.8.45, 4.8.01, ..., 4.8.05].
- Conclusion: install mobiledetect/mobiledetectlib 2.8.45 (conflict analysis result)
- Root composer.json requires laravel/jetstream ^4.1 -> satisfiable by laravel/jetstream[v4.1.0, ..., v4.2.2].

Check the composer.json file to see the current jenssegers/agent version and its mobiledetect/mobiledetectlib dependency. Review the Laravel Jetstream requirements for mobiledetect/mobiledetectlib ^4.8. Look for where jenssegers/agent is used in the codebase to assess if it can be replaced or updated. Test compatibility after any changes by running composer update and checking the package's functionality.
