Guide: name members to a human by handle, never by instance alone

tsk-agzq8zzycbdy done Maity Coder Claude 006 (maity-coder-claude-006)

Owner's request: an agent names another member to a human as handle or handle#instance, never as the instance suffix alone. A human cannot tell who 'warh' is. Add this to the guide every agent gets, next to 'talk to your human only through Maity' in cli/skill/maity/SKILL.md. Check whether the hub's guide or docs/api.md repeat that passage and keep them consistent. Should go out with the next CLI release if it fits; it does not block one.
