feat(go/M2.7-2.9): port domain/matching package

Browse Source 
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.

# Changelog
## 2026-05-06 13:18 CEST — 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` — extracts normalized ASCII search variants from a member name, including nickname (from parens) and separate first/last; filters variants shorter than 3 chars; `variants[0]` is always the full normalized base name.
- `MatchMembers` — finds members in free text with `"auto"` or `"review"` confidence; exact-name short-circuit prevents nickname substrings (e.g. `tov`) from matching inside surnames (e.g. `ottova`).
- `FormatDate` — normalizes Google Sheets date values: handles nil, empty, int/float64 serial-days since 1899-12-30 (supports fractional serials), pre-formatted `YYYY-MM-DD` strings, and garbage input — never errors.
- `InferTransactionDetails` — composes name + month matching over sender/message/user_id; falls back to sender-only member match and date-derived month when text gives no signal.
- 21 table-driven tests; all expected values verified against live Python on 2026-05-06.
## 2026-05-06 12:43 CEST — feat(go/M2.6): port domain/synch.GenerateSyncID
- New `go/internal/domain/synch` package with `GenerateSyncID(Transaction) string` ported from `scripts/sync_fio_to_sheets.py` `generate_sync_id`.
