* Fix#2812: Intel Macs skip wgpu's indirect-call validation shaders
Metal's Intel compiler aborts on wgpu's indirect-validation compute shaders
("Compiler encountered an internal error"; MTLCompilerService crashes in
reportUnsupportedMaxWorkGroupSizeMetadataError), the device is lost inside
request_device and GridCraft exits before its window opens. GridCraft issues
no indirect draws or dispatches, so on Intel Macs the instance leaves
VALIDATION_INDIRECT_CALL out; WGPU_VALIDATION_INDIRECT_CALL=1 turns it back
on. Every other platform keeps wgpu's default. Same as WordCraft (#2652 there).

* Review: test that WGPU_VALIDATION_INDIRECT_CALL=1 still turns it on; qualify the doc line
The override is checked in a child test process with the variable set, since
tests can't set environment variables without unsafe code. The revision line
no longer says Intel Macs start: OpenCore Legacy Patcher Macs on macOS 15 can
still fail on the MSL version (#1116).

A formula calling a Google-only function (GOOGLETRANSLATE, QUERY,
ARRAYFORMULA...) opened as #NAME? where the wrapper had shown the cached
value, as Excel does. The XLSX reader now unwraps a cell formula only when
every function inside is known: read_xlsx_with takes the predicate (the
xlsx crate can't depend on the function library) and the engine passes
gridcraft_calc::is_known_function. Unwrapping stays in the reader so shared
formulas are shifted from the unwrapped master.

Google Sheets' XLSX export writes a formula that uses a function it thinks
Excel lacks as IFERROR(__xludf.DUMMYFUNCTION("<formula, quotes doubled>"),
<cached value>). GridCraft showed the wrapper as the formula.
fmla::from_file, which every cell formula read goes through (plain, shared
master and t="array"), now recognises exactly that shape: IFERROR (with or
without _xlfn.) of a single-string __xludf.DUMMYFUNCTION call, any case.
If the string parses, the formula inside replaces the wrapper, as the whole
formula or nested in a larger one (parenthesised unless it is a single
operand). The cell keeps the file's cached value.
Bounded on hostile input: inner text over MAX_FORMULA_LEN is not parsed,
only one level is unwrapped, and a result that no longer parses (nesting
past the parser's limit) keeps the file's formula. Text that doesn't parse
keeps the wrapper.
Saving writes the real formula with Excel's _xlfn. prefixes, as Excel does
with the _xlfn functions it knows. Keeping cached results for functions
GridCraft can't calculate is #2770 and not part of this change.

The default still reads a string with typed input, which is en-US: "05.04.2026"
from a dd.mm.yyyy export became 4 May, "2.500" became 2.5, and the command said
nothing (#2255). `parse: false` (PR #2267) lets a caller keep the text, but a
script that does not pass it still cannot notice the change.
The result now names them: `converted` lists the strings typed input read as a
number (dates and times included), a boolean or an error, with the cell, the
input and what the cell shows, and `convertedCount` is the total. It is capped
at 20 entries and 32 characters per string, so a big write does not put a second
copy of its data in the result. A string written as a formula (`=1+1`) and a
leading apostrophe are not conversions. `cells` and the default reading of the
values are unchanged.
Two `parse: false` fixes from the review of #2267:
- An empty string clears the cell, as `null` and the default path do. Storing an
empty text cell left a cell that is not blank: `values: [["", ""]]` gave
COUNTA 2 and ISBLANK FALSE.
- MCP `write_range` takes `parse`, so an agent can opt out too; the tool's
description and docs/mcp.md say so.
Tests: the issue's examples under both settings, the report and its cap, the
empty string, and an XLSX save/reopen that keeps the text as text and the
default's date as a date.
formulas.recentlyUsed scanned the session journal for cell.set inputs.
It missed formulas entered by range.* commands, lost them when the
journal dropped its oldest entries (a large file open or a long script
is enough), and started empty in every session. The Function Library's
Recently Used menu and the Insert Function dialog list what it returns.
- Prefs::recent_functions (a new engine module, recent.rs) holds the
ten functions most recently entered in a formula, newest first.
Session::execute updates it for every cell.* and range.* command it
journals, from any source (the interface, the control channel, MCP or
a script). It reads at most 2,000 of the formulas a command enters,
starting from the last one; formulas longer than Excel's limit are
skipped. formulas.recentlyUsed
returns it. It never reads the journal back, so the journal's caps do
not affect it.
- The list is kept with the other engine preferences (prefs.json, the
browser's storage on the web), so it survives a restart as Excel's
does. It is read leniently: a malformed value loses only this list. A
fresh install starts from common functions.
The Insert Function dialog is titled "Insert Function", as in Excel (it
said "Formula Builder"), and gains a working category list: Most
Recently Used, All, then each category in Excel's order. A category may
be given by label or by engine id, so a Function Library menu or the
control channel (ui.dialog.set) opens it on one, and a new search
switches to All. The dialog keeps its translated labels and its search
in the interface language. Each row shows the function's name and its
category in two columns; the category column starts after the widest
name shown, so a long name in any font or formula language stays clear
of it. A function counts as recently used once its formula is entered,
not when OK is pressed. The unused "Formula Builder" translations are
removed.
Tests: engine unit tests for reading functions from formulas (strings,
unknown names, over-long and malformed formulas), the formulas a
command enters (newest first, within the budget), the ten-name list
and the lenient read of prefs.json; tests/it/recently_used.rs for
cell.set and range.setValues from the session, a failed command, a
cleared journal and a save and reload of the preferences. UI tests for
the menu's order and the dialog's title, categories, engine-id
category, search and OK, and for the category column with a wide font.
The Function Library group was a big Insert Function button followed by
AutoSum and seven big category buttons that all drew the same icon, the
widest group on the Formulas tab. It is now laid out as Excel lays it
out when the window is not wide enough for a big button per category:
big Insert Function and AutoSum buttons, then the categories as
labelled small buttons in columns of three:
Recently Used Text Math & Trig
Financial Date & Time More Functions
Logical Lookup & Reference
- The category buttons draw a new code-drawn icon, Icon::FnBook, a book
whose spine and glyph (star, coins, question mark, letter, clock,
magnifier, theta, dots) take the category's colour from the theme's
category palette. icons::paint_accent draws an icon with an accent
colour, and widgets::small_button_accent is a small button that uses
it; small_button is unchanged for its callers.
- AutoSum stays the big split button: the icon inserts SUM, the label
and arrow open the AutoSum menu, which now reads Sum, Average, Count
Numbers, Max, Min and More Functions… and is shared with Home ›
Editing. Its tooltip names the control only, so the shortcut comes
from the platform lookup (Alt+= on Windows and Linux).
- Each category menu lists its functions with their descriptions on
hover and ends with Insert Function…, which opens the dialog with
that category. More Functions cascades into Statistical, Engineering,
Cube, Information, Compatibility and Web. Recently Used lists what
the engine's formulas.recentlyUsed returns.
- The function categories, the function list (built once) and the menus
live in a new function_library module; the dialog's category labels
come from it.
- keytips.json gains MR for Recently Used, Excel's sequence. Labelled
small and big buttons report their label to accessibility.
- The one-line labels (Date & Time, Lookup & Reference, Math & Trig,
More Functions) replace the two-line keys in every interface
language, with the same words. Recently Used is translated in Czech,
German, Spanish, French, Japanese, Korean, Portuguese, Russian and
Chinese; the other languages show it in English, their fallback.
Tests: tests/it/function_library.rs covers the layout (columns of three
level with the tab's other columns), each category menu and its Insert
Function… row, the More Functions cascade, the AutoSum split button and
its menu, and the MR key tip. A ribbon unit test keeps Command-key
glyphs out of the ribbon's text. chart_resize picks the chart menu's
Delete now that Home › Cells' Delete has an accessible name.
