AnnotationManagerTyped extension

Typed convenience layer over the JSON transport on AnnotationManagerInterface.

These wrap the *Json methods and parse Instant JSON into the typed Annotation models. They are platform-agnostic: at the getAnnotationsJson boundary all platforms emit spec Instant JSON. Parsing is defensive (Annotation.tryFromJson) so one malformed annotation never fails a page.

Implemented as an extension (not default methods) because the platform managers implements the interface; a custom adapter customizes behavior by overriding the *Json transport methods, which these delegate to. See documentation/typed-annotations-cross-platform.md.
