Multi-GPT

Run local parallel-reasoning Multi GPT through the async `multi_gpt_start`, `multi_gpt_status`, and `multi_gpt_cancel` MCP tools. Use when the user asks for Multi GPT, Super GPT, GPT Pro-style multi-agent reasoning, multiple independent approaches with merge/judge/refine, complex design comparison, deep code or architecture review, long-form problem solving that benefits from Planner to parallel Solver to Refiner to Loop to Organizer orchestration, or canceling a mistakenly started Multi GPT job. Do not use for simple one-shot advice; use Codex sub-agents or normal reasoning instead.
