## Motivation and Context The MCP specification defines an optional `annotations` field on both the `Resource` and `ResourceTemplate` types, but the Ruby SDK is the only official SDK that does not wire it up — TypeScript, Python, and PHP all implement it. https://modelcontextprotocol.io/specification/2025-11-25/server/resources#annotations The `MCP::Annotations` class already exists; this commit connects it. The field accepts an `MCP::Annotations` instance rather than a raw hash, for consistency with other typed fields and to get `lastModified` key normalization for free. ## How Has This Been Tested? Added tests in `test/mcp/resource_test.rb` and `test/mcp/resource_template_test.rb`: - `#to_h` omits `annotations` when nil - `#to_h` includes `annotations` when present (also asserting that `last_modified` is serialized as `lastModified`) The full unit suite and RuboCop pass locally. ## Breaking Changes None. `annotations:` is a new optional keyword argument defaulting to `nil`, and it is omitted from `#to_h` output when not set.
