feat(flow): add interactive AI puppet to FlowScreen

- Added puppet component modules: PuppetView, FlowPuppetSlot, and type definitions

- The puppet supports actions such as idle/smile/jump/shake/think, with a default smile.

- FlowScreen integrates puppet slots; it automatically uses the "think" function when sending messages and allows for interactive actions like Smile/Jump/Shake.

- The code is independent of the existing chat logic and does not affect existing functionality.
