Clip a file chart's series block to the sheet's used range and refuse blocks over the
insert.chart cell cap, so whole-column references can't build ~1M series.

chart.switchRowColumn did nothing on a chart read from a file: only
charts made by insert.chart keep their source range. Without one, the
command now takes the block the series' names, categories and values
span (when they're all on one sheet), and keeps it.
formula::parse("Sheet1!$D$1#") failed with "unknown error literal".
A # right after a cell reference is now the spill range operator: it
evaluates to the anchor's current spill range, or #REF! when the cell
doesn't spill (or its spill is blocked). Its users depend on the
anchor, so they recalculate when the spill grows or shrinks. Names can
use it.
Files have no # operator: like Excel, the writer stores A1# as
_xlfn.ANCHORARRAY(A1), and the parser reads that back as A1#.
The parser upper-cases function names, so =Double(4) showed as
=DOUBLE(4). Calls of LAMBDA names are now spelled like the name when
a formula is entered and when a file is read.
formulas.createFromSelection ignored bottom and right, and replaced any
workbook name with the same label without asking. Bottom-row and
right-column labels now name the cells above and to their left. An
existing name is kept and listed in the result's skipped, unless
replace is set (Excel asks; a command doesn't open dialogs).
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.
On a protected sheet a formula formatted Hidden still showed with Show
Formulas on, matched Find in formulas, and showed in the formula bar
when a cell of its spill range was selected.
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.
Resolve input styles from the destination cell, row or column before
parsing. Preserve inherited alignment, borders and number formats for
single-cell and bulk entry, including text paste and array formulas.

Narrow columns with tall, upright headers (mark sheets) set both a text
rotation and Wrap Text. The wrap path drew the text flat and returned before
the rotation was applied, so headers came out as 3-4 character fragments.
- Rotated text no longer takes the flat wrap path. Upright (+/-90 deg) text
wraps to the row height, its lines stacking across the column; other
angles keep one line, as before.
- Downward text was anchored at the bottom-left and ran out of the cell
(over the row headers); it now starts at the top, one block-height in.
- Upright text no longer overflows into empty neighbours: its width is its
line height, and the overflow repainted their gridlines.
- Print/PDF gets the same three fixes.
Tests: ui-egui interaction test (shapes drawn at +/-90 deg, inside a
one-column clip) and a print test (every text block on the page rotated,
a few long lines each). Each failed before the fix.
