## Why
Prompt layouts use inconsistent selection styles, and long content can crowd out choices and keyboard hints in small terminals.
## What changed
- Apply shared picker surfaces, selection highlights, accent colors, and shortcut styling across approval, question, startup, and session prompts.
- Reuse numbered picker rows with wrapping and selected-item visibility. Bound folder paths to preserve trust disclosures and choices, prioritizing the repository root when space is limited.
- Give multiline prompts a shared layout for rendering and cursor placement, with Escape hints that reflect Vim mode.
- Present local providers as vertical choices with inline status, adding arrow-key and `j`/`k` navigation plus `1`/`2` selection shortcuts.
## Testing
Add snapshots and regression tests for narrow and short viewports, long trust paths, multiline cursor placement after resizing, selection styling, provider shortcuts, and confirmation behavior.
