Feature Request: Support for "of:accepts:xmtp" Metadata Property

[Mr94t3z]

Feature Description

I'm proposing the addition of a new metadata property, specifically of:accepts:xmtp, to enhance the capabilities of Frog with XMTP protocol support. This property would specify the version or date until which the protocol is accepted, providing clearer communication and compatibility expectations between clients.

Current Behavior

Currently, Frog does not explicitly support or recognize the of:accepts:xmtp property in its metadata handling. This limits the framework's ability to interact with projects that use XMTP or similar protocols requiring version control and forward compatibility.

Example Metadata

1. HTML Meta Tags:

   <meta property="of:accepts:xmtp" content="2024-02-01" />

2. OnChainKit Metadata:

   export const metadata: Metadata = {
     title: "Your frame metadata",
     description: "Your frame metadata",
     openGraph: {/* Your frame metadata */},
     other: {
       ...frameMetadata,
       'of:accepts:xmtp': '2024-02-01',
     },
   };

3. Frog Metadata?
