Trim to length
Propose cutting whole sentences until a project reaches a target length. Deterministic: runs the same composition capability a Sigma turn uses, in review mode, with no model. proposals[] holds zero or one signed proposal in the /v1/sigma/turns shape; send proposals[0].proposal unchanged to POST /v1/sigma/proposals/apply, and its edits[].turnId to POST /v1/sigma/revert. An empty proposals means nothing needed changing and summary says why. Free: nothing runs on an engine or a provider.
