Refactor TUI exit keybindings: Ctrl+D to quit and Enter to exit after render

[tjazerzen]

Summary

• Simplified exit behavior by using Ctrl+D for immediate exit
• Changed Ctrl+C to only copy selected text (does nothing without selection)
• Removed the double Ctrl+C to quit logic and associated quit-pending state
• Added Enter key to exit TUI after rendering completes
• Footer dynamically updates to show render-finished keybindings

Changes

Keyboard Shortcuts

• Ctrl+C: Now only copies selected text; does nothing if no text is selected
• Ctrl+D: New keybinding for immediate exit without confirmation
• Enter: Exits the TUI after rendering has finished
• Removed: Double Ctrl+C to quit workflow
• Removed: ESC to cancel quit

Visual changes

Code Changes

  • Updated keybindings (Ctrl+C → copy_selection, Ctrl+D → quit, Enter → enter_exit)
  • Removed _quit_pending state management
  • Replaced action_smart_quit() with simpler action_copy_selection()
  • Added action_enter_exit() to allow exiting with Enter after render completes
  • Added _render_finished flag to track render completion state
  • Updated on_render_completed() to set flag and update footer
  • Removed action_cancel_quit() and _refresh_footer() methods

• tui/components.py:

  • Updated footer text to show new keybindings
  • Added RENDER_FINISHED_TEXT constant for post-render footer
  • Added show_render_finished() method to dynamically update footer
  • Removed quit-pending state management from CustomFooter
  • Simplified component by removing update_quit_state() method

• tui/widget_helpers.py:

Test Plan

• Verify Ctrl+C copies selected text in the TUI
• Verify Ctrl+C does nothing when no text is selected
• Verify Ctrl+D exits the TUI immediately
• Verify Enter does nothing during rendering
• Verify Enter exits the TUI after rendering completes
• Verify footer updates from "ctrl+d: quit" to "enter: exit" after render finishes
• Verify footer displays correct keybindings
