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.

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.

Alt+H, O, A (AutoFit Row Height) and Alt+H, O, I (AutoFit Column Width)
ran nothing when Alt was still held for H, as Excel allows: any key with
Alt down cancelled keytips. KeyTips now tracks the left Alt key, and a
letter typed with it held that continues a known sequence is handled as
a keytip letter. Other Alt combinations still cancel; AltGr (right Alt)
and macOS Option are unchanged (#1864).
fr.rs and sr.rs translated three `context|label` keys with the context
kept ("Options|Général", "Opcije|Opšte", "Options de la feuille|Affichage"
...). `Language::tr` shows a found translation as it is, so File › Options
section headings and the Sheet Options "View" checkboxes showed the prefix.
The values now hold only the label.
Tests: `translations_never_show_the_context_prefix` (no catalog shows a `|`
for any key) and `translated_options_headings_show_no_context_prefix`
(File › Options in French and Serbian); both fail on main.

rowGrandTotals is the Grand Total row under the report and colGrandTotals the
Grand Total column at its right. Both were mapped the other way round; a
GridCraft round trip hid it, but an Excel file with only one grand total opened
with the other one.
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.

A line that is not a JSON object with a string method, including an HTTP
request line, bytes that are not UTF-8 or a line over 64 MiB, gets one
error reply and the connection closes before anything after it is read.
Request lines are read with a bound instead of buffering them whole.
A hostile file could abort any process that opens it: a cell formula of a
million `%` (`1%%%…`) or a 200,000-term sum parsed into trees deep enough to
overflow the stack when printed, saved, evaluated or dropped, even in release
builds. Postfix operators (`%`, invoking a result) built their nesting in a
loop that the 256-level limit did not see.
- `parse` refuses formula text longer than Excel's 8,192 characters
(`MAX_FORMULA_LEN`, counted in characters, the leading `=` excluded). This
also bounds the depth of the left-deep trees long operator chains build.
- Each postfix `%` and each call of a result counts towards the nesting limit.
- A file's formula that is refused keeps its text and cached value, as other
unparsable formulas do.
Regression tests: formula (small-stack thread: long `%`, invoke and operator
chains are errors; the limit counts characters, not bytes) and xlsx
(`hostile_formula_text_does_not_overflow_the_stack`: open, save and drop a
workbook with such formulas and a defined name on a 1 MiB stack). Both abort
with a stack overflow without the fix.

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.
Closes#1050

Brings the branch up to upstream's main (180 more commits). One conflict,
and one thing the merge needed that was no conflict:
- docs/ui-parity.md: every line of both sides is kept, as upstream's own
merges keep them (its heading has three lines now); this change's
heading line and history row come first.
- crates/ui-egui/src/i18n/pt.rs: upstream's Portuguese catalog gained a
"Yesterday" of its own, with the same word ("Ontem"). The one this change
added is left out: a second arm for the same text is unreachable.
Gate: all eight steps, 1548 tests.
