feat: Make mode selection a select

[Twixes]

TL;DR

I was always inclined to click the modes selector, and I couldn't. This is a GUI after all.

Now I can.

I hijacked your PRs @Twixes, love this 100%! 🥇

I disabled it by default and put it behind a setting, when they enable the setting I also give them a talking to about safe AI usage 😆

Similar flow to claude code w/ claude --dangerously-skip-permissions, will be a once-on type thing for power users. We are starting to onboarding early adopters and Jonathan working on revamping the permissions persistence and prompt, so I wanna make sure we have good happy paths here.

Was able to fix merge conflicts, tests + lint, we should be able to get this in soon! Let me know any thoughts/feedback
