Wraps ask-minimax-run to run a MiniMax M3 implementation sub-session in an
isolated git worktree, with the prompt assembled from a planner work item
(cp_cli item + documents + parent/siblings). Supports --dryrun, --collect,
and --upload, per the pattern used for the 2026-09-10 seven-worktree batch
(see agent-runtimes memory/gotchas-minimax.md).
