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.

SHA-256 dedup hash from sync_fio_to_sheets.py generate_sync_id.
Key subtlety: Python str(float) emits "500.0" for whole-valued floats
and switches to scientific notation at |f|>=1e16 or |f|<1e-4 —
replicated via formatAmount using 'f'/'e' format selection.

Port scripts/infer_payments.py parse_czk_amount to Go as
internal/domain/money.ParseCZK. Preserves the Czech-locale heuristic
(comma = decimal sep; 2+ dots = thousand seps; single dot = decimal)
and returns (float64, error) so callers can opt into Python's
silent-zero contract via v, _ := money.ParseCZK(s).
All expected values verified against live Python on 2026-05-06.

Three-pass regex parser matching python/czech_utils.py parse_month_references:
1. Numeric slash notation — "11+12/2025", "01/26"; 2-digit year → +2000
2. Dot notation — "12.2025" (4-digit year only)
3. Czech month names — range walk (listopad-leden wrap logic) then
standalone with m≥10 → defaultYear-1 heuristic; longest-match
alternation (sorted desc by name length) handles cervenec vs cerven
35 table-driven tests, all expected outputs verified against live Python
on 2026-05-05 before locking. Plan at
docs/plans/2026-05-05-2337-go-rewrite-m2-2-parse-month-references.md.

Adds internal/domain/czech.Normalize, the first pure-domain function in
the Go rewrite (M2 milestone). Matches Python czech_utils.normalize byte-
for-byte: NFKD decompose via golang.org/x/text/unicode/norm, drop Mn-
category combining marks (unicode.Mn, not IsMark, to match Python's
unicodedata.combining() semantics), then strings.ToLower.
Includes 13-case table-driven test; all inputs spot-checked against the
Python implementation before locking. Adds golang.org/x/text v0.36.0 as
first external dependency.

Feature work now goes on feat/<slug> branches; Claude pushes and prints
the Gitea compare URL for the user to open the MR. Exceptions documented
for small fixes and typo tweaks.

- Add canonical_member_key() in match_payments.py to normalize names via
NFKD + lowercase + whitespace-collapse before ledger lookup; resolves
payments attributed to e.g. "Maria Maco" to canonical "Mária Maco".
Emits logger.info when a non-canonical cell is rescued so sheet typos
are visible in logs without losing the payment allocation.
- Extend group_payments_by_person() in app.py to accept member_names and
re-key raw-payment groups under the canonical attendance-sheet name so
the modal's Raw Payments debug section also finds the row correctly.
- Add raw payments collapsible section to member detail modal in adults.html
and juniors.html for debugging payment attribution issues.
- Remove 4 obsolete tests targeting routes /fees, /fees-juniors, /reconcile,
/reconcile-juniors that no longer exist; add test_match_payments.py
covering canonical key equivalence and reconcile() tolerance end-to-end.

match_members() now short-circuits on whole-word full-name hits and
uses word-boundary regex everywhere else, so a nickname that is a
substring of another member's surname (e.g. "tov" inside "ottova")
no longer produces false positives. Adds tests/test_match_members.py.
