Summary: - Add ConversationGazeModifier to hold a focused eye/head pose while AI Agent is listening or speaking. - Attach and remove it from Xiaozhi display status transitions. - Expose normalized target input for future face or audio tracking. Rationale: - Gives StackChan a stable conversation gaze behavior without adding heavy vision dependencies. Tests: - . /Users/xurui/esp/esp-idf-v5.5.4/export.sh >/tmp/idf554_export.log 2>&1 && idf.py build Co-authored-by: Codex <codex@openai.com>
