fix: handle raw newlines in JSON-LD strings

Sites like Bluesky emit JSON-LD with literal newline characters inside
string values (technically invalid JSON). Add sanitize_json_newlines()
fallback that escapes control characters inside quoted strings before
retrying the parse. This recovers ProfilePage, Product, and other
structured data that was previously silently dropped.
