InputManager class

Orchestrates keyboard input routing between host app and palettes.

InputManager is the central coordinator that:

• Tracks which entity (host or palette) has keyboard focus
• Routes captured keys to focused palette AND any unfocused palettes that want them
• Handles click-outside behavior

Example:

// Get the InputManager from PaletteHost
final inputManager = PaletteHost.instance.inputManager;

// Palette shows and takes focus
inputManager.registerPalette('slash-menu', InputBehavior.menu());
inputManager.setFocus(PaletteFocused('slash-menu'));

// Later, palette hides
inputManager.unregisterPalette('slash-menu');
inputManager.setFocus(HostFocused());
