Module window_manager 

Multi-window manager for the terminal emulator

This module contains WindowManager, which coordinates multiple terminal windows, handles the native menu system, and manages shared resources.

The implementation is split across sub-modules for clarity:

• cli_timer — timing-based CLI options (exit-after, screenshot, command send)
• update_checker — periodic/forced update checks and desktop notifications
• window_close — window teardown and resource reaping
• window_lifecycle — window creation and monitor positioning
• window_session — session save/restore and arranged-window creation
• menu_actions — native menu event dispatch
• settings_actions — settings window open/close, event routing, and live config propagation (R-27)
• coprocess — coprocess start/stop and state sync to settings UI
• scripting — script start/stop and state sync to settings UI
• arrangements — save/restore/manage window arrangements
• config_propagation — apply config changes from settings to all windows
• config_renderer_apply — renderer-specific settings application (split from config_propagation)
