Overview

lyman update — walks the manifest (never the filesystem) and reconciles every managed artifact against the current lyman release. Three tiers per docs/design/deployment.md: managed artifacts either replace silently (pristine) or halt with a structured message (modified/missing); owned artifacts are the user's and are skipped; ejected artifacts get a one-time advisory. Artifacts not in the manifest are never even looked at.
