Investigate a project's current state, propose plan items to cut or fold together, and execute the trim once confirmed. Use when a plan has accumulated cruft, the user asks to "tighten the plan", "what can we cut", "what's still relevant", or after a phase ships and the surrounding plan has drifted. Companion to user-pm (read-only snapshot); plan-trim writes.
