Spec conformance: meta support and spec updates (#415)

Browse source 
* feat: add _meta to content blocks and embedded resources; update schemas

* feat: set default protocol version; add _meta to content blocks/resources; update schemas

* chore: format content.rs via rustfmt

* chore(protocol): keep LATEST at 2025-03-26 per review until full 2025-06-18 compliance

* feat(prompt): add constructors with optional meta for image and resource

- Keep text helper; meta is currently ignored for text until schema supports it.

* refactor(prompt): simplify constructors so meta is optional; remove duplicate non-meta variants

* fix: modify code comment about version

* refactor(prompt): rename meta parameters in new_resource function for clarity
