Plans every occupied plate of every .nest file in a local folder the way
Plan Cutting does after clearing lead-ins and cut-offs, and writes one
JSON line per plate with its outcome, warnings, fallbacks, expansions,
time and spacing pairs. It is how the reliability sweep found its
failure classes over 1,260 production plates; the nests and the report
stay outside the repository, and the test skips without the folder.
