Convert an analysis just done in-session into a resumable, traceable plan file — frontmatter + dashboard + execution log + lots whose closure is a re-runnable shell command — then run the execution pass (/pick-workflow then /pick-model) so a FRESH session can orchestrate it lot by lot. Use when the analysis is done but too big to execute here, when context is filling and the work must survive a /clear, or on 'turn this into a plan', 'give me a resumable/traceable plan', 'workstream plan', 'make this resumable', 'hand this off to a fresh session'. WRITES the plan; never executes it.
