CI installs the stable toolchain, and Rust 1.95's clippy fails
'cargo clippy --workspace --all-targets -- -D warnings' on main:
- xls/mod.rs: collapsible_match. The XF record's size check becomes a
match guard; a full table still ignores the record (the catch-all arm).
- passthrough_tests.rs: nonminimal_bool. !is_some_and(x) is written as
is_none_or(!x).
No change in behaviour.

rowGrandTotals is the Grand Total row under the report and colGrandTotals the
Grand Total column at its right. Both were mapped the other way round; a
GridCraft round trip hid it, but an Excel file with only one grand total opened
with the other one.
Excel counts TRUE/FALSE and error values as strings in a cache field's
<sharedItems>. GridCraft wrote containsString="0" (and counted booleans and
errors as separate kinds for containsMixedTypes) for such columns, which made
the file unopenable in Excel, even when the column wasn't used in the pivot.
Add Stats::strings() (text, booleans, errors) and use it for
containsSemiMixedTypes, containsString and containsMixedTypes.

A hostile file could abort any process that opens it: a cell formula of a
million `%` (`1%%%…`) or a 200,000-term sum parsed into trees deep enough to
overflow the stack when printed, saved, evaluated or dropped, even in release
builds. Postfix operators (`%`, invoking a result) built their nesting in a
loop that the 256-level limit did not see.
- `parse` refuses formula text longer than Excel's 8,192 characters
(`MAX_FORMULA_LEN`, counted in characters, the leading `=` excluded). This
also bounds the depth of the left-deep trees long operator chains build.
- Each postfix `%` and each call of a result counts towards the nesting limit.
- A file's formula that is refused keeps its text and cached value, as other
unparsable formulas do.
Regression tests: formula (small-stack thread: long `%`, invoke and operator
chains are errors; the limit counts characters, not bytes) and xlsx
(`hostile_formula_text_does_not_overflow_the_stack`: open, save and drop a
workbook with such formulas and a defined name on a 1 MiB stack). Both abort
with a stack overflow without the fix.

A category range two or more columns wide beside a column of values (year beside month, Excel's
multiLvlStrRef) was read as one flat list: 36 rows in two columns became 72 categories, the
series sat in the left half of the plot and the years and months shared one row of labels.
Saving wrote the range as a plain strRef, so Excel lost the two-level axis too.
- gridcraft_core::category_levels: the shape of a category range beside its values (levels are
columns when the points run down the rows, rows when they run along the columns; up to three
outer levels), shared by the chart and xlsx crates.
- ChartData.category_levels: the outer levels, nearest the labels first, one entry per category,
non-empty where a group starts. resolve fills it; a single column is unchanged.
- render: the outer levels in rows under the labels, a group's name centred under its categories
with a separator at each boundary; in bar charts in columns beside the labels.
- xlsx: <c:cat> written as multiLvlStrRef with the level caches (innermost first), so the axis
survives a round trip.
Tests in core (shapes), chart (resolve and layout for columns, bars and a row of values) and
xlsx (written XML, read-back, stability, a single column stays strRef). chart-parity, gaps § 4
and the ROADMAP progress log updated.

- restore closing braces the line-level merges of side-by-side tests dropped
- new ChartData literals carry the palette field
- the filter-menu shortcut passes the row with the column
- #688's tab tests account for #851's All Sheets button
- Serbian margins for the ruler-margin labels

[@Col] is only Excel's display shorthand. Written verbatim into cell formulas and calculatedColumnFormula, it made Excel repair the file and drop the tables.
A legacy array formula in a .xls file ({=FREQUENCY(...)}, {=TREND(...)}) is
stored as one ARRAY record plus a FORMULA record per cell of its range, each
with the cached result. The importer attached the formula to the anchor cell
but kept the cached values in the other cells as plain constants. On
recalculation the formula then found its range occupied and returned #SPILL!.
The .xlsx reader already drops those cached results; the .xls reader now does
the same once the formula is attached, and keeps the values when the formula
could not be imported.

Chart sheets (a sheet that holds one chart; Move Chart > New sheet, F11) were
skipped on open, and their chart sheet, drawing, chart, style and colour parts
were dropped with them because the pass-through treats those kinds as content
GridCraft rewrites. Saving a workbook lost every chart sheet.
They are now kept as they were: the <sheet> entry (name, visibility and its
place among the worksheets), the chartsheet part and everything behind it,
byte for byte, written back in place. The workbook's other sheet positions
(active tab, print areas, scoped names) are computed with the chart sheets
counted. A chart sheet is left out on save when the chart is no longer
valid for the workbook: a sheet it plots was deleted or renamed, or a
worksheet took its name.
write_csv visited every position of the used range and appended to one growing
String with no limit, so two cells far apart (A1 and XFD1048576) asked for
about 16 GiB of commas. The output is now capped at 512 MiB: a lower bound
(delimiters and line ends of every row) is checked before anything is
allocated, and the text written so far is checked after each row. Over the
cap, write_csv returns IoError::TooLarge naming the rows, columns and limit,
and Save As / Export CSV and TSV report it without writing a file. Accepted
exports are unchanged. write_csv now returns a Result.
