Tyrel HavemanandClaude Opus 5.5 e177bf1c44 calc: hardening: overlong digits, NaN indexes, REGEXREPLACE output (#2163, #2162)
- 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.

Marco Arnulfo 4d2e8e3455 Functions: database functions evaluate computed criteria (part of #737)
A formula under a criteria label that names no field is evaluated for each record: its relative references move from the first record to that record, and the database labels name the record's fields, as in Excel. The calc evaluator passes the criteria reference to the database functions through Ctx::computed_criterion.
