feat: upgrade bubbletea, bubbles, and lipgloss to v2

- Migrate import paths from github.com/charmbracelet/* to charm.land/*/v2
- Replace tea.KeyMsg with tea.KeyPressMsg in all update handlers and tests
- Replace View() string return type with tea.View using declarative AltScreen
  and MouseMode instead of tea.WithAltScreen()/tea.WithMouseCellMotion()
- Replace tea.WindowSize() with tea.RequestWindowSize in Init()
- Remove tea.ClearScreen from all tea.Batch() calls (removed in v2)
- Replace lipgloss.SetColorProfile(termenv.TrueColor) with
  tea.WithColorProfile(colorprofile.TrueColor) in NewProgram options
- Replace ti.Width assignments with ti.SetWidth() method calls
- Update Redraw() to send tea.WindowSizeMsg{} instead of removed tea.ClearScreen
- Update test assertions to check view.Content instead of view directly
- Remove github.com/muesli/termenv dependency
