Version bump `0.8.4` → `0.8.5`.
### Fixed
- The R binding's golden-fixture parity test now skips gracefully when the shared `testdata/golden` fixtures are not bundled with the package — standalone r-universe / CRAN builds package only `bindings/r`, so the repo-root fixtures are unreachable there (this was failing the r-universe build of 0.8.4). The parity stays enforced by the repository CI, where the fixtures are present. (#257)
Bump touches the manual release touchpoints only (`Cargo.toml`/`Cargo.lock`, Python/Node/Java/C#/R manifests, lockfiles, `SECURITY.md`, `CHANGELOG.md`). docs/webpage version strings are left to `sync-about.yml` on the tag.
