Add a configurable reviewer phase to all create-plan variants (claude-code,
codex, opencode) that sends the plan to a second CLI/model for iterative
feedback (max 5 rounds). Supported reviewer CLIs: codex, claude, cursor.
Add new Cursor Agent CLI variant with full skill, templates, and
workspace-discovery-based prerequisites (.cursor/rules/).
Update README and docs/CREATE-PLAN.md with Cursor install/verify,
reviewer CLI requirements, and supported reviewer CLIs table.
