Return a copy of this Resource with any fields newer than the
negotiated protocol version stripped, so the wire output stays valid for
the peer's version. The 2024-11-05 Resource type carried only
uri/name/description/mimeType/annotations/_meta. Later fields
are version-gated: BaseMetadata.title and Resource.size were introduced
by 2025-06-18 / 2025-03-26 respectively (both absent from 2024-11-05), and
Resource.icons by 2025-11-25 (absent from every earlier version, present
in draft which is >= 2025-11-25). Annotation sub-fields are themselves
version-gated: audience/priority existed in 2024-11-05 but
Annotations.lastModified was introduced in 2025-06-18, so annotations are
projected via Annotations.forVersion. Mirrors Tool.forVersion /
Prompt.forVersion.
