crates/layout/src/math.rs: main already centres &-less rows (#2617); kept main's code and added the PR's two tests.
ROADMAP.md: main already has the #2617 log row; the PR's duplicate row dropped.
* #2617: centre equation-array rows without &
A row with no alignment mark sat in the first column and was right-aligned
to it, widening that column and pushing the aligned rows right (Word's
"First Property of Radicals" case equation). Word centres such a row in the
array; it no longer widens the aligned columns.

* #2617: review — test a lone eq-array row wider than the aligned columns

A thin outline as wide as the equation and as tall as its line, a grip over
its top-left corner and an options strip inside its right edge that opens the
equation menu; the argument the caret is in is shaded. Replaces the faint grey
shading around the equation alone.

- Math straight in the body or a cell (m:oMathPara/m:oMath without w:p,
allowed by EG_BlockLevelElts) gets its own paragraph instead of vanishing.
- mc:AlternateContent Requires="m" picks the equation, not its fallback.
- Inside an equation, runs in w:hyperlink, w:fldSimple, w:dir, w:bdo and
mc:AlternateContent are kept (EG_PContentMath); depth stays bounded.
- w:sym, w:noBreakHyphen and Symbol-font text in math runs become Unicode.
- Layout: n-ary operators, delimiters, accents and group characters the math
font lacks use a fallback font instead of a missing-glyph box.
- Coverage test reads every ECMA-376 §22.1 element and checks no argument's
text is dropped; tests for body-level math, Requires="m", symbols, hostile
nesting and the font fallback. Parity docs and progress log updated.

A row of an m:eqArr with no `&` was right-aligned at the first column edge and counted into the
first column width, shifting the wider rows. Per Word, such a row is centred across the whole
array and takes no part in the column widths. Regression test eqarr_rows_without_an_align_marker_are_centred
fails without this. Closes#2617.
The first glyph is math italic 𝑦 only when a font has it; FreeBSD CI has none, so
it shapes as plain y. The test is about line breaks and indents, not the glyph.

A display equation wider than its column ran off the page. It now breaks
at top-level binary operators and relations (never inside a fraction,
radical, script or matrix), filling each line greedily; a term wider
than the line overflows instead of breaking inside.
- Break before the operator by default, or after it, or repeated on both
lines, as the document's m:brkBin says; m:brkBinSub picks how a minus
repeats.
- Continuation lines are indented by m:wrapIndent (one inch by default)
or set flush right with m:wrapRight.
- Manual breaks (m:brk on a run) start a new line; m:alnAt aligns it at
an operator of the first line.
- DOCX: m:mathPr in settings.xml and m:brk in math runs are read and
written back. Documents without them save as before.
- Inline equations, numbered equations and m:jc alignment are unchanged.
Tests: layout (a long sum wraps within the column with indented
continuation lines; after/repeat modes; manual breaks and alnAt; short
equations stay on one line; hostile break input) and DOCX round-trip.

* M5.5: Word equations (OMML) import, lay out and save like Word
Equations were flattened to plain text on import. Now OMML is read into a
math tree (fractions, scripts, radicals, n-ary operators, delimiters,
functions, limits, accents, bars, boxes, equation arrays, matrices,
phantoms), laid out with the OpenType MATH table (Cambria Math when
installed, else STIX Two Math and other open math fonts), drawn to screen
and PDF, and written back as the original OMML. Display equations sit on
their own centred line. insert.equation parses the linear format into
structure.

* M5.5: equation editor like Word's — Equation tab, in-place editing, # numbers
Insert › Equation now opens an equation for in-place editing, with the
Equation tab: ready-made equations, Unicode/LaTeX input and conversion
(professional ↔ linear), Normal Text, eight symbol sets, and the eleven
structure galleries (fraction, script, radical, integral, large operator,
bracket, function, accent, limit and log, operator, matrix) with tiles
rendered by the math engine. Typing builds up like Word (a/b, x^2, √, ∑…
then space), Math AutoCorrect turns \alpha, \sqrt… into symbols, Tab moves
between empty slots, arrows/Backspace work through structures, and the
right-click menu has structure commands (fraction type, radical degree,
limit position, matrix rows/columns, remove brackets…). A trailing #(n)
numbers a display equation with the number at the right margin; # alone
numbers it automatically. DOCX output keeps numbers Word-compatible.

* i18n: equation editor strings in Spanish, Brazilian Portuguese and Ukrainian
The catalogs that landed on main after #191 was opened lacked the Equation
tab and equation command labels.

* Equations: our own names and order for the built-in equations
Clean room: the ready-made equation list used another product's gallery entry
names and order. Same formulas (and ids), with our own descriptive labels,
grouped by subject (geometry, algebra, calculus, trigonometry, probability).
