HSP-capable variant of the built-in `codex` sandbox kit -- the same `codex` CLI, plus a wrapper entrypoint and sidecar shim (this repo's `codex/`) that expose the Harness Steering Protocol (hsp/1) by attaching to Codex's own `app-server` as a second JSON-RPC client and steering the live thread the human TUI is on. Built to test/demo the Agentic Platform's custom-kit-only HSP capability (APT-1382). Everything below this point through the `agentInstructions` block is copied verbatim from the built-in `codex` kit spec (docker/sandboxes, sandboxlib/agentkits/agents/codex/spec.yaml) -- see this repo's root README.md, section 10 ("Codex CLI adapter and sandbox kit: codex-hsp-kit"), for the diff summary; the only changes are this description, `sandbox.image`, and `sandbox.entrypoint`.
