gitnexus-lfg — plan → gate → work → review

Thin orchestrator over three existing skills. It adds no engineering logic of its own — it sequences gitnexus-plan, gitnexus-work, and gitnexus-review, with the user deciding at the plan gate. Run every lane by actually invoking the named skill (read its SKILL.md and follow it); never inline a summary of what the skill would have done.
