claude-code: an agent proposes a shared instruction section, and every node takes it only on the operator's warrant (hq ADR 0274)

Shared instructions were the terminal's alone since hq issue 340, because the tool runner cannot tell an
agent from the operator. The operator channel now proves who answered, so an agent may propose a section;
each node proves the router's warrant against the exact text itself and keeps what it approved in its own
file, so nothing written to the bus becomes active.
