The 10,000-character header spec was bounded, but each &A, &F or &Z
added the whole sheet name or path again, and a JSON workbook's sheet
name has no length limit. A field that would take a section past
64 KiB is now left out.
edit.fillSeries with dateUnit "weekday" stepped one calendar day at a
time, so a large step cost work proportional to its size for every
cell. It now uses add_weekdays, which moves whole weeks arithmetically.
* functions: match TEXTSPLIT/TEXTBEFORE/TEXTAFTER delimiters through an index, within a work limit
The delimiter matcher compared every delimiter, duplicates included, at
every position of the text. Delimiters are now deduplicated and grouped
by the character a match is anchored on, and a search that would
compare more than 100 million characters returns #VALUE!.
* functions: pass float literals in the delimiter test
The importer kept every cell of a row and only charged their text to
the 64 MiB allowance when the row finished, so one row of long cells
could hold up to 16,384 MiB before being refused. Text is now charged
as each cell finishes; the row charges only its repeats.
* functions: MODE counts through an index, FREQUENCY bins by binary search
MODE/MODE.SNGL/MODE.MULT searched the list of distinct numbers seen so far
for every input, and FREQUENCY scanned the sorted bins for every data value,
so both were quadratic in computed arrays. MODE now keys counts by value
(-0 folded into 0, NaN never merged) and keeps first-occurrence order;
FREQUENCY finds the first bin at or above each value with partition_point
over the order it already sorts. Results are unchanged.
* address review: FREQUENCY keeps NaN data in the overflow bin and NaN bins empty
* calc: list each dependent once when a change spreads
* calc: check the dependency closure against a walk of every cell
Random graphs of single-cell, narrow and wide range reads (some removed or unsettled), random seeds and changed areas: the closure with shared taken records and area lookups equals the one listing every dependent of every changed cell.
* calc: cap the text one & over arrays may build in all
* address review: concatenation over arrays stops at the byte budget without reserving the whole broadcast
Every source record scanned the filter's whole selection, so a large
selection multiplied by many records was slow even when nothing passed.
Each filter's labels are lowercased into a set once per computation.
wrap_lines split an over-long word by re-measuring and copying the
rest of the word for every piece it cut, and only checked its line
limit once the word was done, so one long word in a narrow text box
cost word length x pieces. Each new word also re-measured the whole
line built so far.
Line and piece widths are now running sums of glyph widths (the same
sum text_width makes), so every character is measured once, and the
line limit is checked while a word is being split. The lines produced
are unchanged; a test compares them with the old wrapper.
Importing a workbook whose sheets share a name rescanned every sheet for
every suffix tried, so a file of repeated names opened in cubic time.
SheetNames keeps the assigned names and the next suffix per stem.
- #3223: sniff the first 64 KiB for a web page and skip JSON and files over the text-import cap, so
every CSV/TSV is no longer decoded in full before the size check.
- #3253: SYLK relative offsets use checked arithmetic (no overflow on R[9223372036854775807]); at
most 1024 column-width records are kept; regression test.
- #3254: a single selected merged cell searches the whole sheet, as one selected cell does.
- #3252: the formula bar's height cap is half the room below the ribbon, not half the window, so
the worksheet stays visible in a short window (CodeRabbit Major).
- #3239, #3244, #3252, #3268: es/de/cs/zh/ko/ru/pt entries for the new interface strings.

Addresses review comment 4456174694: the drag/expand cap was half the
window, so in a 400 pt window a ~195 pt bar left the grid about 1.6 pt
under the status bar and sheet tabs. The cap is now also limited by
the room left under the ribbon, keeping the status bar, sheet tabs,
column headings and two rows below the bar.

Addresses the follow-up in review 5753664551: the protection test had
no range exception, so a regression that refused locked notes and
links inside an Allow Edit Range would have passed. The new test
clears a link in a range without a password, is refused a note in a
password range, then clears both once that range is unlocked.
Test: engine tests::clearing_links_and_notes_keeps_allow_edit_ranges.

Addresses review comment 4455670315:
- Clear Hyperlinks and Clear Comments removed links and notes on
locked cells of a protected sheet: protection compares stored cells
only, so their removal went unseen (for stored cells too, and now
for unstored ones since the whole range is cleared). `clear` now
refuses a locked cell's note or link with locked_cell_error, which
keeps Allow Edit Ranges and session-unlocked ranges.
- A removed note or link on a cell with nothing stored wasn't added
to the changed cells, so a recorded macro's footprint missed it.

tests::clearing_links_and_notes_records_their_cells.

Addresses review comment 4455436875: `clear` clipped each range to the
sheet's used range (stored cells) before removing links and notes, so
a link from a file on an empty cell outside it was left in place, and
nothing was removed on a sheet with no cells. Notes and links are now
cleared over the whole range; cells and merges still only within the
used range.

point_move wrote a bare reference, so on another sheet Shift+arrow after a header
drag turned 'Other sheet'!B:D into B:E, which reads as the formula's own sheet.

In Page Layout view the "Click to add data" pages are faded after their cells are
painted, which all but hid the band on them. The band goes on again over the fade.
Tests also cover Page Layout view and frozen panes.

After a drag over C:E, point_cell held C and no anchor was set, so Shift+Right
moved the wrong end and gave D:E. The drag now records the pointer's end as the
moving one and the opposite corner as the anchor, so it gives C:F, and rows work
the same way.

Addresses review comments 4455115540 and 4455115557. The parser stores
`'Sheet'!Name` as `Sheet!Name` with the sheet already unquoted:
- Evaluator::name split it at the first `!`, so a series named
`'a!b'!Title` showed #NAME?.
- chart_name unquoted it again, trimming spaces, so a chart reference
to `' Sales '!Data` was saved as `Sales!Data`.
Both now split at the last `!` and look the sheet up as is.

On a wide table the eye loses its place following a row from the active
cell. File > Options > General gets "Highlight the active cell's row", off
by default: a tint across the whole row of the active cell, over the fills
and under the text, in Normal and Page Layout views. It is a preference for
every sheet and workbook, so nothing goes into the file, the workbook does
not become dirty and there is no undo step.

A press on a header while a formula waits for a reference inserted C:C, but the
drag that followed did nothing, so dragging from column C to E left C:C. The drag
now follows the pointer, as it does over cells, in either direction and for rows
too, keeping the sheet qualifier, the earlier arguments of a Ctrl press and the
far end of a Shift press.
