/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).
