Adds standards/ai-agents.md: how an agent session runs — instruction
precedence, fresh standards at session start, autonomy boundaries,
implementation and verification discipline, secrets and untrusted
content, provenance trailers, context economy. Complements the
AI-assisted development policy (governance) with session operations.
Adds EX-0005 to the exception register: agents push directly to the
personal-automation repositories (second-brain, nix, Praetor, Jellyfin)
where that is the designed workflow, with compensating controls; and
K22-AGENT-04 requires agents to resolve workflow conflicts through the
register instead of silently violating or refusing.
