/**
 * Shared mid-turn follow-up policy for ACP adapters (Grok, Kimi, OpenCode).
 *
 * Compatible follow-ups land on the same ACP session. If a `session/prompt` is
 * already in flight, Anima cancels it first so the follow-up starts immediately
 * instead of waiting for a natural `end_turn`. Cancelled-prompt assistant chunks
 * are rolled back so they do not leak into the final Slack reply.
 *
 * Session methods, permissions, model selection, and activity mapping stay in
 * each adapter — this module only owns the interrupt + text-isolation contract.
