Feature/UI layout changes

[simoncollins]

Got basic question and response layout working. Also snuck in support for markdown rendering including GFM and added nice styling of response HTML with tailwind's typography package:

Added progress spinner:

• Reactored app.tsx into separate components and introduced Zustand for state management
• Pull some logic out into custom hooks.

Known issues / remaining work:

• Response area doesn't scroll if text overflows
• Settings and chat buttons in top right do nothing except pop up alert box
• Need to remove focus from text area and shrink font size when query is running and other little UX improvements
• Need to reset to question mode when the user clicks into the question area again
• Need to add copy button to copy response to clipboard
• Need to add support for syntax highlighting of code.
• Need to make the response text styling better - should be inverted colors to match dark mode

Hey @Dax911,

can u justify why u wanted to use zustand for this esp since the context and state is already so tightly bound to the rust backend

Good question and I did mull over whether it was worth it. I initially implemented it without but found that I was prop drilling a bit to use state in different component subtrees once I split stuff from App out into different component, so I figured it was worth it for simplifying the logic without adding too much overhead.

Definitely a good question about the split between Rust side and Tauri side state though.
