build-program

Builds the next training program for one client from their own MSB data (training, check-ins in full text, PRs, plan and the lens when present): reads the msb://import-rules resource and the coach's library, previews the import JSON with msb_preview_program, shows the coach the summary and every new library movement, and saves it with msb_create_program as an invisible draft only on the coach's go.
