Codex alpha adds gated subagent tool inheritance and keeps user restrictions in handoffs

Codex 0.162.0-alpha.1 contains a disabled-by-default flag that lets fresh V2 subagents inherit client-defined dynamic tools without copying parent history. Its reviewed changes also retain root user restrictions in Guardian handoff context, subject to existing message limits, and follow MCP tool-list pagination in legacy protocol mode. These are verified prerelease implementation changes, not universally enabled capabilities or a new model.
