Enhance CLI terminal integration and output handling in InkApp. Introduce terminalService for managing PTY backend, including resizing and updating terminal output. Implement ANSI stripping and tab expansion for accurate line rendering. Improve state management for terminal, logs, and LLM output, ensuring responsive UI updates and error handling during input submission.
