CLAUDE.md: reorganize Key Design Decisions into categorized sections covering architecture, data, integrations, templates, S&F, security, cluster, UI, monitoring, code organization, and Akka.NET conventions. Add docs/plans and AkkaDotNet to project structure. README.md: add technology stack table and scale summary. Update all 17 component descriptions to reflect refined designs. Update architecture diagram with load balancer, 2-node annotations, protocol connections, and component details. Add links to AkkaDotNet reference docs and design plans.
Audit logging was absorbed into the Configuration Database component (IAuditService), making the separate Component-AuditLogging.md redundant. Also added tool usage guidance to CLAUDE.md for Codex MCP model selection.
