Makes OPA build and pass its tests on Go 1.27, while keeping Go 1.25 and 1.26 working. JSON output is unchanged on every supported version. Go 1.27 json package honours `encoding.TextAppender`. Many v1 ast types implement AppendText to build their Rego string cheaply, so on 1.27 they would have marshalled as Rego text. Files built only with 1.27 now implement MarshalJSONTo. Library users should keep using `json.Marshal` etc. The MarshalJSONTo methods are implementation details, are absent from 1.25 and 1.26 builds, and may change. --------- Signed-off-by: Anders Eknert <anders.eknert@apple.com> Signed-off-by: Charlie Egan <charlie_egan@apple.com> Co-authored-by: Charlie Egan <charlie_egan@apple.com>
