Read package metadata, lockfiles, and config files to fingerprint the upgrade surface.

Compute constrained, package-aware upgrade steps for the supported route.

Attach official migration references and curated risk areas to selected packages.

Find high-signal repo-level patterns that are known to complicate upgrades.

Turn dependency intelligence and repo findings into an ordered upgrade plan.
