When BubbleTea has to render lines longer than the terminal length (and the terminal does the line wrapping) it sometimes bugs out and renders incorrectly. This happens both with markdown formatted and plaintext output.
Solution
Since we only ever render wide markdown formatted code, limit the width of the resulting code to the terminal width (plus some buffer). This gets rid of the permanent output artifacts in the terminal (still some flashing, but that's inherent to BubbleTea). Fixed: 93dde89edbe7818f2fdfedc3527a585359
Context
On a narrow terminal window where rendered output wraps to the line below, sometimes output jumps around and creates "sticky" artifacts that end up in the terminal output.

Given that this only occurs on narrows terminal windows where lines wrap around I'm guessing this might be an issue how BubbleTea handles rapid updates to the rendered markdown output. Also going to try validating that there's no rogue tea.Print or actual prints messing things up.
Task
Find root cause of jumpy output and fix, so it is stable and leaves no artifacts.
