LLM now routes based on agent self-declarations (description + skills)
injected at runtime. Adding a new agent automatically makes it
available to Nexus without any manual update.

Add explicit routing table: apt/update/system tasks → debian.local,
deploy agent reserved for deploying new agents only. Prevents LLM
from routing 'apt update' or 'mettre à jour' to the deploy agent.
