Pull Request Overview

This PR refactors the codebase to improve import organization and reduce circular dependencies by:

• Moving the KimiCLI class from src/kimi_cli/__init__.py to a new dedicated src/kimi_cli/app.py module
• Relocating InputFormat and OutputFormat type definitions from kimi_cli.ui.print to kimi_cli.cli
• Converting top-level imports in cli.py and agent.py to lazy imports to break circular dependencies

The Generator type hint is incomplete. It should specify all three type parameters: Generator[None, None, None] representing the yielded type, the send type, and the return type.

Suggested change

	def _app_env(self) -> Generator[None]:
	def _app_env(self) -> Generator[None, None, None]:

The mcp_configs parameter is missing from the docstring. It should be documented with its type, purpose, and default value.
