option to hide or shorten the permission-mode indicator below the input

the permission-mode banner shown below the input box (e.g. "⏵⏵ accept edits on (shift+tab to cycle)") is helpful at first but gets noisy once you know the keybind.

would be nice to have a setting that either:

1. hides the banner entirely (e.g. "hidePermissionModeHint": true)
2. or shows a compact form — just the icon + mode name, no parenthetical hint and no "on" suffix (e.g. ⏵⏵ accept edits or just ⏵⏵)

context: it shows on every screen, takes up a row, and the (shift+tab to cycle) hint in particular feels like onboarding text that could fade after first use.

happy to PR if a maintainer can point me at the rendering call site.
