/**
 * ProgressMdAdapter is a ProgressPort that keeps a LIVE progress.md tracker on
 * disk. It owns a ProgressTracker, applies each event, and rewrites the single
 * progress file — so progress.md is always current, never the dead skeleton the
 * master-plan skill used to leave behind. The tracker is exposed so the run
 * loop can fold a per-stage handoff note in before the next stage.
