fix(tui): allow native text selection/copy by disabling mouse capture by default

Mouse reporting (tea.WithMouseCellMotion) captures terminal mouse events
and prevents standard click-drag selection and copy. Keep mouse support
off by default and add a --mouse flag for users who prefer wheel scrolling.

- add --mouse CLI flag
- only enable WithMouseCellMotion when --mouse is set
- update README usage examples and key bindings
