Jan Novak e596f0000e feat(go/M2.7-2.9): port domain/matching package
New go/internal/domain/matching package porting three helpers from
scripts/match_payments.py:

- BuildNameVariants: normalized ASCII variants from a member name (nickname
  in parens, last/first split, len<3 filtered); variants[0] is always the
  full base name — MatchMembers relies on this invariant.
- MatchMembers: auto/review confidence matching with an exact-name
  short-circuit pass that prevents nickname substrings (tov) from firing
  inside longer surnames (ottova); common-surname filter for review tier.
- FormatDate: nil/empty/""/serial int/float64 (since 1899-12-30, fractional
  days supported)/YYYY-MM-DD passthrough/garbage → never errors.
- InferTransactionDetails: composes BuildNameVariants+MatchMembers+
  ParseMonthReferences; falls back to sender-only member match and
  date-derived month when text carries no signal.

21 table-driven tests; all expected values verified against live Python
on 2026-05-06. go-build, go-test, go-lint all clean.
