Update headless command execution to use the new architecture: - Removed CommandResult import (no longer needed) - Headless mode now creates an App instance and uses cmd_context() - Commands are parsed and executed via the registry, effects applied through app.apply_effects() instead of command::dispatch() - Made cmd_context() public so headless mode can access it - Updated persistence save to use app.model instead of direct model Tests updated to use ExecuteCommand instead of QuitCmd, with proper buffer setup for command parsing.
