GridCraft imports XLSB (#101) and ODS (#100) files, and #321 added both
to the Linux and Windows "Open with" lists, but the macOS Info.plist
still declared only .xlsx, .xlsm, .csv and .tsv, so Finder's Open With
didn't offer GridCraft for them. Add two CFBundleDocumentTypes entries
(Editor, rank Alternate) with the UTIs macOS reports for these files,
plus an imported UTI for .xlsb like the .xlsm one. A test now checks
that the macOS and Windows packaging offer the same file types.

In 0.5.0 a click anywhere on the Home ribbon's Paste button (label,
icon or dropdown arrow) froze the app for good. home() called
paste.secondary_clicked() inside ctx.data_mut(); after any click egui
answers that with ctx.input(), which takes the context lock the closure
already holds, so the UI thread waited on itself. Sampling the hung
0.5.0 process on macOS shows the main thread parked in
RawRwLock::lock_exclusive_slow under Context::write <- data_mut <-
ribbon::home. #272 moved the query out of the closure; it landed after
the 0.5.0 release, which is the build both reporters used.
No test ever clicked the Paste button itself, which is how this
shipped. The new test clicks it, then opens its menu with a secondary
click and picks Paste Values, on a worker thread with a timeout so a
regression fails instead of hanging the run. With #272 reverted it
fails (egui's debug lock check panics after 10 s); with it, it passes.
The Paste button gets an accessible "Paste" name so the test (and
screen readers) can find it, the same way Pictures and Border presets
are named.
With the freeze gone, the button still did not do what it says: it
pasted GridCraft's own copy only (GridState::system_clipboard was never
assigned), so text copied in another app gave "Nothing to paste." The
ribbon button, its options menu's Paste, the cell and header context
menus and the macOS Edit menu now read the system clipboard through a
new paste_text host service and paste it like Cmd/Ctrl+V does, falling
back to GridCraft's own copy when there is no text (or no service, as
on the web). Asking egui for the clipboard instead (RequestPaste) was
tried and stalled the macOS event loop until the next input event.

Builds on the Solver of #327. data.solver takes reports: [answer, limits]
and writes them on new sheets before the model's sheet once a solution
is found. The Answer report lists the objective and variable cells with
their original and final values and each constraint's value, formula,
status (Binding or Not Binding) and slack; cells are named by the
nearest labels to their left and above. The Limits report minimises and
maximises each variable with the others held at the solution, under the
model's constraints, and gives the objective at both ends (Simplex LP
and GRG Nonlinear, without integer constraints).
data.solverReport writes the reports for a given solution and model,
so data.solver's result (which now carries the original values and the
model) can be passed to it as is. The Solver Results dialog offers the
two reports; they are written after Keep Solver Solution or Restore
Original Values.
Builds on the Solver of #327. method: evolutionary runs a genetic search
for models that aren't smooth: tournament selection, blend crossover and
Gaussian mutation inside the variable bounds, feasibility-first ranking
and integer rounding, then a compass search around the best member. It
stops when the population converges, when the best member stops
improving for a number of generations, or at the evaluation budget. A
seeded generator makes runs repeatable. Population size, mutation rate,
random seed, convergence and Require Bounds are options; the method and
its options are saved in the hidden solver_* names. The Solver
Parameters dialog offers the method.
XLSX: strip _xlpm. from LET/LAMBDA parameters on read, keep line breaks in table columns, allow leading backslash in table names

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).

OK on the untouched field says the password is incorrect instead of
asking again; the Backstage closes once the workbook opens; app.open on
the control channel takes a password and never opens the dialog. Control
protocol docs cover file.open {password}.

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.

Checked against Excel-cached TEXT() results in number- and text-format test workbooks: 226 of 352 TEXT cells mismatched before, 0 after.

Grouped rows and columns now get Excel's outline band beside the headers:
a bracket per group, a -/+ button on the summary line and level buttons
in the corner. The buttons run data.hideDetail / data.showDetail and the
new data.showLevels, so they undo. Hide Detail marks the summary line
collapsed, Show Detail keeps inner groups that were collapsed on their
own, and Group / Ungroup take by: rows|cols. Show Detail and Hide Detail
are on the Data tab and in the Data menu, the group shortcuts are listed
as Alt+Shift+Right / Left, and shortcut lookup reads navigation keys by
their logical key so the numpad arrows work.

wgpu's default DX12 compiler (Auto) loads the first dxcompiler.dll on the
DLL search path. GridCraft ships none, so another program's copy is used;
without a matching dxil.dll its 'DXIL signing library not found' warning
fails wgpu's internal compute pipelines, the device is lost and the app
exits before the first frame. Pin FXC (part of Windows) unless
WGPU_DX12_COMPILER asks for another compiler.
