`formulas.evaluate` (behind `gridcraft-cli eval` and MCP's `evaluate_formula`) turned any
formula that didn't parse into #NAME?, so `=SUM(1;2)` looked like an unknown function. It now
parses the way `cell.set` does (missing closing parentheses are added) and returns the same
errors: "There's a problem with this formula: expected `,` or `)`, found Semicolon", or the
wrong-argument-count message. An unknown function still evaluates to #NAME?, as in Excel.
text_width sums in u64; an all-zero or non-finite dash array is written as
solid ([] 0 d); stroke widths are clamped to >= 0 (NaN -> 0); drawing calls
with non-finite or non-positive geometry return before storing anything.

Info strings were WinAnsi; PDF text strings are PDFDocEncoding or UTF-16BE.
Printable ASCII stays a literal string; anything else is a <FEFF...> hex
string. Info strings are capped at 1024 characters.

home.rowHeight, home.autofitRowHeight and data.ungroup change row hidden
state without marking the edit structural, so SUBTOTAL(101-111) kept a stale
value. Found by the command-sequence fuzz (seed 3).

home.deleteRows/deleteColumns used only the last selected area. They now
take every area (or a comma list like "3:3,7:8"), merge them and delete
from the last to the first inside one edit, so it is one undo step.

XLSX headerFooter kept only oddHeader/oddFooter: a workbook whose header is on a
different first page (differentFirst + firstHeader) or on even pages showed no
header, and saving dropped it. The model now keeps the first/even headers and
footers and the differentFirst / differentOddEven / scaleWithDoc / alignWithMargins
flags; XLSX reads and writes them; the PDF and the Page Layout view use the right
pair per page; in-place editing edits the page's own pair, and the Header & Footer
tab has Different First Page and Different Odd & Even Pages. pageLayout.headerFooter
takes the variants and a page: odd|even|first for one-section edits.
Insert › Header & Footer now switches to Page Layout view and edits the first
page's centre header, as in Excel, instead of opening the codes dialog.

On macOS the UI font (SF) has no Hebrew and no Hebrew fallback face was
found, while cells in Arial drew it: the formula bar showed boxes. The
interface families now carry the cell face ahead of the script fallbacks,
and the macOS Hebrew candidates include ArialHB.ttc / SFHebrew.ttf /
LucidaGrande.ttc.

Text boxes ignored a:rPr (size, bold, italic, typeface, fill, outline),
a:pPr algn, a:bodyPr anchor and spPr/a:ln/a:noFill. They are now read into
Shape::format, drawn on screen and in PDF, and written back.
