Delete Cells built the references' edit and then discarded it, so
references into the deleted cells didn't become #REF!, and Insert Cells
treated the shift as a move of everything below, so =SUM(A1:A5) didn't
grow to A1:A6 when A3 was inserted.
Two new structural edits, InsertCells and DeleteCells, adjust a
reference like inserting/deleting rows (columns) when it lies within the
shifted columns (rows), and leave it as it is otherwise, as Excel does.
Formulas, defined names, chart series, conditional-format, validation,
table and print-area ranges, notes, links and sparklines follow.
Only cell.set checked protection. The check now runs where every edit
is committed: an edit that changes the value or formula of a locked
cell on a protected sheet is refused with Excel's message, whichever
command made it (clear, paste, fills, setValues, replace, goal seek,
sort, insert/delete cells...).
Inserting and deleting rows and columns follow the protection's
options, and deleted lines must not hold locked cells.
Moving a sheet left its sheet-level names on whatever sheet took its
index, and copying it shifted nothing and copied no names. Moving now
re-indexes name scopes, and a copy gets copies of the sheet's names,
referring to the copy, as in Excel.
Deleting a sheet left names that referred to it pointing at nothing;
they now become #REF!. formulas.deleteName honours scope, and the Name
Manager's Delete passes it.
Excel anchors a floating object to the grid in one of three ways, stored in the
file as the drawing anchor's `editAs`: "move and size with cells" (twoCellAnchor,
the default), "move but don't size with cells" (oneCellAnchor / editAs="oneCell")
and "don't move or size with cells" (editAs="absolute"). GridCraft had no such
concept: xlsx import dropped `editAs`, export always wrote a plain twoCellAnchor,
and sorting/filtering never moved an object — so pictures stayed put when their
rows were reordered.
Model: add `AnchorMode` on `Anchor` (serde default = MoveAndSize, so existing
documents round-trip unchanged).
xlsx: read the anchor kind and `editAs` into the mode; write it back out
(editAs="oneCell"/"absolute" as Excel does).
Engine: sorting now moves objects anchored inside the sorted body with their
lines, re-fitting "move and size" objects, keeping "move but don't size"
objects' size, and leaving absolute ones pinned. Structural insert/delete
honours the same rule (previously it moved every object's cell unconditionally
and ignored shapes). New `object.setAnchorMode` command sets an object's mode;
`arrange.selectionPane` reports it.
Tests: sort moves images with their rows; absolute objects stay put across a
sort and a row delete; move-only keeps its size; the mode survives an xlsx
round-trip; the drawing fixture parses all three anchor kinds.
