Previously, when using @mcp.resource(uri, meta={...}), the meta dict
was only forwarded to individual TextResourceContents/BlobResourceContents
items, but not to the ReadResourceResult itself.
This fix forwards the first non-None meta from content items to the
ReadResourceResult._meta field, enabling use cases like MCP Apps that
need CSP metadata at the result level.
