fix: emit one json-ld script per schema object

A single ld+json script holding a top-level array crashes naive
structured-data consumers (Safari extension content scripts) that read
parsed['@context'] without checking for arrays. Emit one script per
object so every payload has a top-level @context, and escape < in the
root layout like the marketing pages already did.
