* engine: bound Advanced Filter, Remove Duplicates, AutoFilter, Circle Invalid Data; one-pass AutoFit; saturating range dimensions
* address review: AutoFit scans each run of adjacent selected columns separately
* address review: report a truncated circle-invalid scan, no spill scan for plain cells in Replace, one pass for many AutoFit runs
* address review: warn in the app when Circle Invalid Data stopped early; Replace test requires success
* address review: the scan note joins an open-time notice; say cell visits
