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).

With values on rows and no column field, the header cell above the data
column reads "Total", as Excel saves it (tabular checked against a real
file).
Σ Values in Columns always comes after the last column field: the column
layout doesn't place it anywhere else, so `pivot.moveField` no longer
stores a position there, the reader ignores where `-2` sits in colFields
and the writer puts it last.
`pivot.changeSource` removes dropped row and column fields one by one so
Σ Values keeps its place ahead of the field it preceded.

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.

Ctrl+Shift+Arrow (and Shift+Arrow, Shift+PageUp/PageDown, Alt+Shift+PageUp/PageDown,
Ctrl+Shift+Home/End, Shift+Home) extend the selection by moving its far corner while the
active cell stays on the anchor. After the move the grid set `ensure_visible`, but the
scroll-into-view step in `grid::show` always targeted `selection.active`, which is the
anchor and is already on screen. So the view never followed the extension past the last
visible row or column.
The keyboard extension paths now also set `GridState::reveal_moving_end`, and the
ensure-visible step then scrolls to `Selection::moving_end()`, the corner opposite the
anchor. `selection.move` now uses that same helper (it had the logic inline) to find where
an extension starts. Other ensure-visible callers (Go To, Name Box, plain moves) still
reveal the active cell.
Regression test: crates/ui-egui/tests/selection_scroll.rs drives Ctrl+Shift+Up/Down/
Left/Right, Shift+Down/Right and Ctrl+Shift+Home/End through real egui key events and
checks that the moving end ends up on screen while the anchor and active cell stay put.

`input` is documented as "text, number or =formula", but only a string
was read; a JSON number was dropped and the command failed (or, on 0.5.0,
silently cleared the cell). The undocumented `value` alias already went
through `json_to_input`. Both keys now share that converter, so numbers
and booleans are entered as typed. The MCP `set_cell` schema types
`input` as string, number or boolean to match its description.

With two or more value fields the Σ Values pseudo-field can sit in Rows
as well as Columns, at any position among the row fields. The model
records it (`PivotTable.values_on_rows`, `values_position`) and the
engine lays it out like Excel in compact, outline and tabular form: one
row item per value field at the Σ Values level, per-value subtotals
("East Sum of Sales") and grand totals ("Total Sum of Sales").
XLSX reads `dataOnRows` and the `-2` field's place in rowFields or
colFields and writes them back; the "values on rows are shown on
columns" warning is gone. `pivot.moveField` moves "Σ Values" between
Rows and Columns or within one, axis field moves keep it in place, and
the PivotTable Fields pane lists it.

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.

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.
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.

- Action::Pending now consults the engine catalog at fire time: silent
no-op while the command is missing, runs it once it exists - no table
edit needed when a future feature lands.
- Stripped stray backticks from 7 pending target ids so catalog lookup
can ever match them.
- gridcraft-engine: doc(hidden) register_test_command hook so UI tests
can prove the go-live path without touching production code.
- Tests: pending_sequences_are_silent_no_ops (no dialog/toast/journal),
pending_sequences_go_live_when_the_command_lands (fake command fires
via its reserved sequence), every_sequence_terminates_without_panicking
(all 413 sequences pressed end-to-end).
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.
