channel-nudge

Hooks-only console-drift detector for the discord/zulip/wechat channels. One Stop hook runs once per turn, reads the transcript once, and checks every channel in a single process — on drift, emits a soft, non-blocking hookSpecificOutput.additionalContext (a verify-before-resend nudge into the drifting instance's next-turn context — instance-facing self-heal, no console banner). CJK codepoints weight-2 toward the 80-char prose threshold so ~40-hanzi answers are caught.
