Clean a messy import

Search, split, deduplicate, filter, sort, and undo while keeping every operation inside one spreadsheet session.

Try this

Select a range and make an edit.
Use the toolbar to apply a data operation.
Undo the operation and continue editing.

How it works

The chrome composes optional UI capabilities around a single backend. This skeleton uses the real worker path so later scenario seeds can demonstrate data tools without replacing the grid architecture.
