Go (go/) becomes the primary implementation. The original Python
version moves to legacy/ and is kept runnable; new features are still
built in both (see the Dual implementation rule in CLAUDE.md).
- git mv app.py, scripts/, templates/, tests/, pyproject.toml, uv.lock
and build/ into legacy/
- Makefile: Python targets point at legacy/, venv in legacy/.venv,
CREDENTIALS_PATH exported for the root .secret/ file
- CI and make image build the Python image with legacy/ as context;
the Makefile is no longer copied into the image
- legacy/.dockerignore moved to the context root so it takes effect
- CLAUDE.md, docs/README.md, Go comments, fixture README, capture
script and VS Code launch config updated to the new layout

/api/version returns each binary's own tag/commit/build_date, which
differs by design between independently built backends. Diffing it
always produces a false positive. Drop it from allRoutes; the route
remains reachable via `make parity ARGS="-route /api/version"`.
Also remove the vestigial `build_meta` allowlist entry (Python returns
the build dict as the top-level response body, not nested under
build_meta, so the scrubber never matched anything).

Adds cmd/parity/main.go: a standalone Go binary that GETs
/api/version, /api/adults, /api/juniors, /api/payments from both
the Python (:5001) and Go (:8080) backends, scrubs an allowlist
(render_time.total, build_meta), and prints cmp.Diff for any
remaining differences. Exits 0 on full match, 1 on diffs, 2 on
fetch/parse errors — CI-friendly for M7.2.
- go/cmd/parity/main.go: flags (-py, -go, -route, -timeout), fetch
helper, allowlist scrubber (dotted-path aware), exit-code logic.
- go/cmd/parity/scrub_test.go: 4 unit tests for the scrubber.
- go/go.mod: promote github.com/google/go-cmp to direct dep.
- Makefile: parity target + help entry.
- Progress tracker: M5.4 ticked; milestone updated to M5 complete.
- Plan archived to docs/plans/2026-05-07-2254-m5-4-parity-binary.md.
