- 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

Excel stores the path of a linked workbook relative to the file that uses it, and rewrites it when the file is saved into another folder. The path was kept as text, so after Save As it named a file next to the new copy: a missing link, or another workbook with the same name. Relative externalLinkPath targets are now resolved against the folder the workbook was read from and written relative to the folder it is saved into (absolute when there is no relative path, on another drive).
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.

apply_filter cloned and sorted the column's numbers for every row it tested,
O(n^2 log n). The threshold is now computed once per criterion with the other
column stats. Adds a test for top/bottom items and percent.

A `;`-separated CSV (the usual CSV where `,` is the decimal separator) was
rewritten with `,` on save: read_csv sniffed the delimiter but the result was
dropped, and save_bytes passed a hard-coded b','. file.save, Save As .csv,
file.exportCsv, file.saveBytes and gridcraft-cli convert all went through it.
The workbook now remembers the separator it was read with
(Workbook::csv_delimiter, set by read_csv) and a CSV save writes it back.
Workbooks not read from CSV, and .tsv/.txt sources saved as .csv, keep `,`.
Regression tests: `;`, `,` and tab .csv round trips byte for byte, new and
.xlsx-origin workbooks save with `,`, and open-by-path + edit + file.save on a
`;` file keeps `;` (also through exportCsv and saveBytes).

Without a password, file.open returns an error carrying
io::PASSWORD_REQUIRED (never a dialog). A decrypted workbook gets no save
path, so Save never replaces the encrypted original.

Restores "Counts whole years, months or days between two dates." and
appends the units, in the multi-line form rustfmt gives a long entry.
Drops the 256-argument test case: the parser already refuses more than
255 arguments, so it never reached the entry check. (993c108's message
says entry "also refuses" them; it already did.)

Model: Series.trendlines (Vec<Trendline>, serde default) with kind
(linear, exponential, logarithmic, polynomial 2..6, power, moving
average 2..255), name, forward/backward forecast, set intercept,
equation / R² display and line colour, width and dash.
XLSX: read and write <c:trendline> in CT_Trendline child order, placed
after dLbls and before the data references in line, bar, area, scatter,
bubble and stock series; unknown types are skipped.
Chart: least-squares fits (transformed for exp/log/power, skipping
non-positive values; polynomials via normal equations on centred,
scaled x with partial pivoting), moving averages, forecasts that widen
the category or x axis, clipping to the plot, equation and R² labels and
legend entries ("Linear (Sales)"). Degenerate data draws nothing.
Engine: chart.addElement element="trendline" adds (type, series, order,
period, forward, backward, displayEquation, displayRSquared) or removes
trendlines; document.inspect lists each chart's trendlines.

FnSpec::accepts holds the arity check (including Excel's 255-argument
limit) that functions::call and the entry check both use, so entry also
refuses 256 arguments to a variadic function. The evaluator's own check
in calc is unchanged.
