feat: Use eye-declare for more performant and flexible AI TUI (#3343)

This PR replaces the mess of custom rendering code in Atuin AI with
[eye-declare](https://github.com/BinaryMuse/eye-declare), and updates
the TUI to feel more terminal-native: output appears inline and persists
in scrollback, so you can scroll up and look at previous conversations
for reference.

The "review" state — which used to exist between the LLM generating a
response and the user either executing or following up — has been
removed; just start typing to follow up with the LLM, or press `enter`
at the empty input box to execute the suggested command.
