Resolver(sgml:) parses the legacy SGML catalog format: PUBLIC, SYSTEM, DELEGATE, CATALOG, BASE, and OVERRIDE entries with -- comment -- delimiters. Replacement URIs resolve against BASE and the supplied baseURI; OVERRIDE YES/NO maps to the prefer-public fallback. Unknown keywords are skipped tolerantly. Feeds the same Resolver as the XML catalog. Part of #86
