Ed Zynda db4be4f9a2 feat: implement full alt screen mode with in-memory scrollback ...

Add ScrollList component for viewport-based message history with lazy
rendering and offset-based scrolling. Implement MessageItem system for
user, assistant, tool, system, and error messages with pre-rendered
styled content from MessageRenderer.

Key changes:
- ScrollList: height-constrained viewport with itemGap support, padding
  to ensure fixed height for sticky bottom layout
- MessageItem implementations with preRendered content from MessageRenderer
- refreshContent() pattern for efficient ScrollList updates
- Mouse wheel scrolling (3 lines per tick) with auto-scroll behavior
- All message types (user, assistant, tool, system, error, extension)
  properly added to in-memory scrollback
- PgUp/PgDn/Alt+Home/Alt+End keybindings for navigation
- Removed tea.Println() calls for alt screen compatibility
- Sticky bottom layout: input, separator, status bar fixed at bottom

Files added:
- internal/ui/scrolllist.go (ScrollList component)
- internal/ui/message_items.go (MessageItem implementations)

Files modified:
- internal/ui/model.go (main integration)
- internal/ui/*.go (alt screen config for components)
