test: add unit tests for pure JsonLdBuilder methods (#33 partial)

- JsonLdBuilderLocalBusinessTest: buildLocalBusiness() null/minimal/custom-type/ partial-address/geo-requires-both-coords cases - JsonLdScriptTagTest: toScriptTag() wraps in ld+json, escapes </ to prevent </script> breakout, and produces valid JSON after unescaping Covers the pure (Factory/Uri/DB-free) helpers that run under the existing minimal bootstrap. The remaining #33 targets (ImageHelper, BatchController, CSV import, content/system plugin integration) need a Joomla test harness.
