Feature request: compact/collapsible permission prompt — option to hide command preview & diff to reduce dialog height

Problem

When a permission/confirmation prompt appears, the dialog is tall — it renders the
full command (or the full Edit diff) inside a large box. On smaller terminals /
the desktop client this pushes the prior conversation and tool output off-screen,
and the prompt area itself isn't scrollable, so I can't see the context I need in
order to decide whether to approve.

Request

An option to render the permission prompt more compactly, e.g.:

• A setting (settings.json) or env var to collapse/hide the command preview and Edit diff by default.
• A keybinding to toggle the preview expanded/collapsed while the prompt is shown.
• A "compact" prompt mode that shows just the tool name + a one-line summary, with the full body available on demand.

Why

The goal is to keep prior context visible while deciding on a permission request.
Today the only workarounds are to eliminate prompts entirely (allowlisting / permission
modes / --dangerously-skip-permissions), which trade away the per-action review the
prompt is meant to provide.
