## Why
Menu layouts and hints vary across TUI flows, and mismatched measurement and rendering widths can clip subsequent choices when descriptions wrap.
## What changed
- Apply shared picker styling across selection menus, with stable columns, descriptions hidden when space is tight, and compact hints derived from configured key bindings.
- Measure rows at their actual rendering width, including caller insets, so wrapped options receive enough space.
- Wrap model menu headers and shortcut capture content, and use the shared panel surface for shortcut capture.
- Indicate clipped headers in non-searchable menus and show the configured `view all` shortcut only when the view supplies one.
## Testing
Add regression tests and snapshots for wrapping boundaries, narrow picker layouts, configured selection and cancellation keys, and clipped approval headers. Verify that copy/export actions retain complete payloads and composer drafts.
