"""Compose one interactive-shell turn from its action/gather/answer adapters.

Adapter-only: binds the shell's action-turn (``action_turn``), gather pass
(``integration_tool_gathering``), and answer (``answer_turn``) adapters to the
surface-agnostic ``run_turn`` engine. Each adapter owns its own binding; this
file only composes them and attaches turn accounting. The injection contracts
live in ``turn_seams``.
