Replace ansi and text wrapping code with ratatui
Replaced ansi related code for tree sitter highlight with direct ratatui::text. Cache the processed text in appstate to remove processing of text for every frame render.Create paragraph instead of list so that scroll and wrapping can be done without external crates. Add caps keys for handle_key_event.
