PERCENTOF = SUM(subset) / SUM(all), written as _xlfn.PERCENTOF.
EUROCONVERT uses the fixed EU conversion rates for the currencies the
function documents, with currency rounding and triangulation precision.

Excel adds up the range that starts at sum_range's top-left cell and has
the criteria range's height and width, whatever size sum_range has. With
A1:B3 = a,1 / b,2 / a,3, =SUMIF(A1:A3,"a",B1) is 4; GridCraft gave 1,
because if_numbers only saw sum_range's values (one cell) and read them
at the criteria positions. Its comment promised the resizing, but by then
the argument was a plain value.
The evaluator has the references, so it now does the resizing, as it does
for OFFSET and INDEX: for SUMIF and AVERAGEIF with three arguments, a
single-area sum range reference becomes resized_sum_range(sum, criteria
height, criteria width), cut off at the sheet's edge. It works across
sheets and through names. The dependency graph records the resized
range, so editing a cell inside it recalculates; when the criteria range
isn't a plain reference the formula is recalculated every time instead.
SUMIFS and AVERAGEIFS keep requiring same-size ranges (#VALUE!
otherwise).
Tests: a single-cell, shorter, wider, longer and horizontal sum range,
whole-column criteria, editing a cell of the resized range, the sheet
edge, another sheet and a defined name, and SUMIFS/AVERAGEIFS size
mismatches. They fail before the fix (1 instead of 4).

Local clippy 1.96 flags pre-existing patterns the code has always had:
manual range-contains comparisons, a dead `|| true` filter and a
simplifiable boolean. None change behaviour; they only clear the lints
so `cargo xtask ci` passes on a current toolchain.
