fix(coordinator): add routing enforcement refusal rule

[diberry]

Closes #853

Problem

The coordinator sometimes does domain work itself instead of dispatching to team members. Some models interpret existing refusal rules loosely.

Fix

Added explicit refusal rule:

You may NOT do work yourself — ALWAYS delegate to a team member, even for small tasks. The only exception is Direct Mode (answering factual questions already in context).

Also confirmed the Init Mode 3-state check (zero roster entries) was already present in all copies — no change needed.
