auto_row_height grew a row for every line break in a cell's text whether
or not the cell wrapped. Excel counts breaks only when Wrap Text is on:
with it off a multi-line value displays on one line and AutoFit gives a
one-line row. A file whose unwrapped cells hold pasted multi-line text
(the shape generating libraries write) opened with tall rows and nothing
visibly tall in them.
The fast path no longer treats a line break as a reason to measure, and
the measuring path lays text out over lines only for a wrapping cell.
Typing a break still turns wrap on (the Alt+Enter rule in cell entry) and
grows the row, as before.
Test: an unwrapped multi-line cell from a file keeps the default height
on open; wrap on grows the row; wrap off returns it; a typed break wraps
and grows. The open-time fit tests from #833 are unchanged.

Templates hide grouped columns as width="0" hidden="1". Show Detail and the level buttons only cleared hidden, so the columns stayed invisible; they now reset a zero size, as Unhide does.
range.fill parsed the input once at the active cell, then put back the old
style of every target that already held a cell, so 5%, $5, 3/4/2026 or
=DATE(...) lost their automatic format there (0.05, 5, 46085), and empty
targets took the active cell's style. Each target now gets what
input_to_cell gives for it (parsed once per distinct style), as typing does.

Undo stored the selection at the moment of undoing (wherever the user had
clicked) in the redo entry, so redo jumped back there instead of to the
cells it changed. The redo entry now keeps the undone step's selection.

file.open takes {csvAsText: true}: a CSV, TSV or TXT file opens with every field as the text
it holds, with no number, date or boolean conversion, so identifiers such as GTINs, SKUs and
ZIP codes keep their digits and leading zeros and save back unchanged. The default is
unchanged. The CsvOptions.parse_values switch already existed in the reader.

The grid's look() and print's cell_look() layered a rule's fill, font and
borders onto the cell style but not its num_fmt, so a cell under a rule with a
number format kept its own. Take the rule's code when it isn't General (in a
differential style General means "not set", as layer_under treats it).
Print also re-formatted every non-General cell from its own style through
display::cell_text; format with the look's code instead, through a new
display::value_text_as that value_text now calls (CSV/Text output unchanged).
Show Formulas keeps cell_text.

forecast_grid re-added every squared residual in each window, O(n×window).
Keep a running sum instead: add the entering term, subtract the leaving one,
and restart at a point without a forecast so windows touching it stay #N/A.

auto_row_height estimated a line of a bigger font by scaling the sheet's
default row height by size / 11. When the sheet's default already fits
that font, the font counted twice: Excel for Mac saves rows of 16pt text
with defaultRowHeight="21" (28px) and no ht, and opening such a file
fitted every row to 40.7px, 1.45 times Excel's height. Rows mixing Middle
and Bottom aligned cells then looked misaligned.
The estimate now scales an 11pt row's height (DEFAULT_ROW_HEIGHT), so
those rows open at 29px, and rows on a 15pt-default sheet still grow to
their font (#833).

Prepare report data before editing so refused reports cannot leave solution cells or the saved model changed. Commit accepted reports with the optional solution and model, retaining array/protection checks and row autofit after sheet insertion.
