Codex Control Plane MCP v0.1.3

Roadmap release for the completed durable control-plane work. This release adds the richer progress journal, runtime inventory, durable thread fork, structured final reports, thread lifecycle tools, workflow goal sync, code review workflows, image inputs, and redacted account, usage, and rate-limit status. It also restores the thin-wrapper comparison guide from the PR #9 contribution by nightcityblade.
