## What changed
- Show latest user-prompt previews beneath saved side-chat titles, fetching previews only for visible entries when the chooser refreshes.
- Keep cached chats available during discovery, show loading and refresh status, and offer an inline retry action on failure.
- Preserve the selected chat across list updates and prevent asynchronous changes or held activation keys from opening an unintended entry. Account for preview rows in paging and mouse selection.
- Explain that side chats become available after the first main-chat message, and let `Ctrl+C` dismiss the chooser while preserving the main draft.
- Separate tabs with noninteractive gaps and improve hover styling for tabs, overflow arrows, and the add button.
## Testing
Extend integration tests and snapshots for discovery failures and retries, refreshed prompt previews, activation guards, variable-height paging, draft preservation, and tab hover states across light, dark, and fallback colors.
