test(agency): the Part L incident scenario end to end, and failure modes

The full incident scenario now runs against the assembled daemon: an operator goal becomes a want to reduce uncertainty, an investigation intention and a diagnosis plan; telemetry is read; logs need authority, so a scoped request with risk, mitigation and fallback is raised and the intention is blocked until an operator grants it; the logs are read with personal data masked and summarised back into cognition; the operator supplies the judgement that a restart should help; a standing commitment turns the restart into a request for approval; after approval the typed capability runs and health is verified rather than assumed; the fault persists, so a prediction error weakens the supporting belief, the plan is replanned into an escalation that reuses the live log grant and does not repeat the restart; once the database is fixed a second approved restart verifies, the procedure is learnt, and "Why did you restart atlas-worker?" is answered from the recorded chain and scores as supported. Changes the scenario exposed: - New operator goals are raised by the goal monitor, so a cycle runs and wants are derived from them. - Intentions link live beliefs about their action's target, so a failed expectation is evidence against the belief it rested on and the plan lists it as an assumption. - Reconsideration reacts to a plan's own intention only; a subordinate "obtain approval" intention shares the plan and previously caused the parent's plan to be closed. - The harness accepts a clock for the executor's verification windows. Further failure-mode tests: a retracted assumption replans a waiting plan away from the restart and withdraws its approval request; conflicting commitments are raised once in a cycle while both stay represented.
