Hovering over the turbo edit code block previously showed a pointer
cursor, and clicking inside would collapse/expand the accordion. This PR
updates the DyadEdit component to use cursor-text and adds
e.stopPropagation() so clicks inside the code block no longer toggle the
accordion.

the code block and updated the cursor to text to signal editing.

toggle.

affordance.
