andon 0.3.0
andon diff — compare two workbook versions, check-aware.
git diff on an .xlsx is noise; spreadsheet-diff tools show every changed cell flat. andon diff old.xlsx new.xlsx classifies each change: a new #REF! called out on its own, numeric moves with a delta and a percent, formula edits, appeared/vanished cells, added/removed sheets. --tolerance hides rounding noise, --json for pipelines, exit codes so CI can gate on it.
