[codex] Fix async recorded move playback

[OzasaHiro]

Summary

Fixes recorded move playback from the async chat path by avoiding the synchronous play_move wrapper when an event loop is already running.

Root cause

ReachyMini.play_move wraps async_play_move with asgiref.sync.async_to_sync. In speak_with_expression_parallel, recorded moves were executed directly inside an async function, which can raise:

You cannot use AsyncToSync in the same thread as an async event loop

Changes

• Extract recorded move resolution into _resolve_recorded_move.
• Keep the existing synchronous execute_recorded_move behavior for sync callers.
• Add execute_recorded_move_async for async callers, using ReachyMini.async_play_move when available.
• Update the immediate and final recorded move calls in speak_with_expression_parallel to use the async-safe path.

Validation

• Ran python -m py_compile emo_v6.py emo_v8.py.
• Ran emo_v8.py --chat --model gemma4:e4b --piper-model models/en-us-blizzard_lessac-medium.onnx --gentle --debug against a local Reachy Mini simulator daemon.
• Confirmed the previous Quick move execution error: You cannot use AsyncToSync... no longer appears during the async chat response flow.
