Typed entry, VALUE and arithmetic now read $(1,234), $ (5) and (5)% as
negative numbers, as Excel 365 does. Parentheses no longer nest: (-5),
((5)), $5% and dates in parentheses stay text. This changes main's
((100)) from 100 to text; the no-recursion guard from #2180 is kept and
its test now asserts the new result.
From the local CodeRabbit review: the result was bounded per match, but
one match's expansion was built whole first, so a replacement repeating
$0 10,000 times over a 32,767-character match allocated about 330 MB
before the check. The replacement is now split into pieces as regex's
Captures::expand reads it (template_expands_like_regex checks they agree)
and appended piece by piece within the bound: 327 MB peak became 7 MB
(regexreplace_bounds_its_result).

- Text coercion: digits too many for a finite number are not a number,
and a fraction must come out finite, so "1 <400 digits>/<400 digits>"
(inf/inf) no longer coerces to NaN (test overlong_digits_stay_text).
- VLOOKUP/HLOOKUP and the D-functions' field index refuse NaN, which
passed their "< 1" checks and became index 0, then underflowed
(test nan_index_is_a_value_error; hostile_inputs_never_panic now also
passes NaN and infinity to every function).
- REGEXREPLACE replaces match by match and gives up once the result can
only be too long, instead of building every replacement first: the
32,767 x 32,767 worst case went from 1.05 GB peak to 7 MB
(test regexreplace_bounds_its_result).
#2165 (MAP's size check) is already fixed on main by the broadcast cap
(836b2698, #2182), whose test covers MAP.
Also adds my contributors/people.toml entry.

Excel 365 reads a dollar sign before accounting parentheses ($(1,234),
$ (5)) and a percent sign after them ((5)%) as negative numbers when the
text is typed, coerced by arithmetic or passed to VALUE. GridCraft gave
#VALUE! for these.
The parentheses branch no longer recurses: Excel reads only an unsigned
plain number or fraction inside, so (-5), ((5)), ($-5), and dates or
times in parentheses are now #VALUE! as in Excel (they used to give 5
or a negative serial). $5% is #VALUE! too: Excel never combines the
currency and percent signs.
