feat(knowledge): add one-call KB improvement job

[drewstone]

Summary

• add runKnowledgeImprovementJob() as the runtime-owned one-call KB improvement loop
• wrap agent-knowledge readiness scoring with runtime supervised updates, candidate workspaces, promotion, and spend/timing measurements
• pass readiness specs, findings, and metadata into the supervised updater so agents know what to fix
