home.insertRows {"rows":"3"} and home.insertColumns {"cols":"B"}
failed with "not a range": only spans such as 3:3 or B:B parsed. The
same went for deleting, hiding, sizing and grouping rows and columns.
A single row number or column letter now means that one line.
home.formatCells documents {style: {numFmt?, ...}}, but the style patch
was merged with the style's snake_case field names, so numFmt (and
borders.diagUp/diagDown) were silently ignored. camelCase keys in the
patch are now renamed to the style's own; snake_case keys still work.
`{"sheet": null, "cols": "Data!B:B"}` was refused as naming a sheet other than `sheet`,
while `target_sheet` and the cell parameters read a null `sheet` as absent. The prefix now
decides, as it does when `sheet` is left out.

home.rowHeight and home.columnWidth take pixels at 96 dpi, the model's unit
(header drags and the Row Height dialog send pixels), but their parameter docs
said points. An agent asking for a 30 pt row got `ht="22.5"` in the file, and
the range check accepted 500 while its message said "between 0 and 409 points".
- The params docs say pixels: `height: 20 (pixels) | points: 15`,
`width: 64 (pixels) | chars: 8.43`, and `{width: 64 (pixels)}` for
home.defaultWidth. Pixel values behave as before.
- home.rowHeight takes `points`, Excel's unit (Row Height dialog, `ht` in the
file), as home.columnWidth already takes `chars`.
- Range errors give the limit in the unit passed: 546 pixels (409.5 points),
409.5 points, 1800 pixels, 255 characters. `chars` is checked against 255,
Excel's limit and the widest column a file holds (it went to 256.4 through
the pixel limit).
- The model's size comments say pixels.

view.freezePanes, home.rowHeight, home.columnWidth, the AutoFit, Hide and
Unhide row/column commands and home.defaultWidth always changed the active
sheet: a `sheet` parameter was silently ignored, so a programmatic caller
laying out a sheet that isn't active changed the wrong one, and `Sheet!`
prefixes on `rows`/`cols` were refused as "not a range".
They now take `sheet` (name or index) like the commands that already use
target_sheet, accept a `Sheet!` prefix on `rows`/`cols` (and on Freeze
Panes' `cell`, which was refused), and refuse a prefix that contradicts
`sheet`. The selection belongs to the active sheet, so another sheet needs
explicit lines or a cell. Freeze Top Row, Freeze First Column and Unfreeze
Panes take `sheet` too. Without `sheet`, nothing changes.

Merge & Center and Merge Cells kept only the upper-left value, but
Merge Across left the other values of each row in place, hidden under
the merge and still counted: with 1 2 / 3 4 in A1:B2, SUM(A1:B2) stayed
10 after Merge Across, where Excel gives 4. Each row's merged area now
keeps only its first value, as the other merges do.
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).

Dragging a header boundary inside a selection of whole columns (rows)
sized only the current area, so with B, D and F Ctrl-selected only the
last-selected one changed. The drag now targets every whole-column
(whole-row) area of the selection, as Excel does; lines outside the
selection, and partial-cell areas, keep their size.
home.columnWidth / home.rowHeight accept a comma-separated list of
areas ("B:B,D:F") so the drag stays one command and one undo step.

Audited the grid, ribbon and editor key handling against Microsoft's
published Windows and Mac shortcut lists. New keymap.rs binds the ones
whose feature already exists: Ctrl+Shift+~!@#$%^&_ number formats and
borders, Ctrl+2-5, Ctrl+Shift+: time, Ctrl+' / Ctrl+Shift+" from the cell
above, Ctrl+L, Ctrl+Shift+L, Ctrl+P, Ctrl+Alt+V, Alt+=, Alt+Down,
Alt+Page Down/Up, Ctrl+Shift+Home/End, Shift+Home, the F-key family
(Shift+F2/F3/F9/F10/F11, F5, F7, F12, Ctrl+F1/F3/F4, Alt+F1, Ctrl+Alt+F9)
and the Excel for Mac variants (Cmd+L/E alignment, Control+E Flash Fill,
Cmd+Option borders, Cmd+Shift+K/J/H/R). Number-format keys match the
physical key; AltGr text never triggers a Ctrl+Alt shortcut. Fixes the
command catalog's wrong shortcut labels and documents the audit.
