Adds a SHOULD for MCP clients to bind the authorization code to their DPoP key per RFC 9449 Section 10. RFC 9449 makes this OPTIONAL; this profile recommends it as defense in depth alongside MCP’s mandatory PKCE. Surfaced by the conformance work in modelcontextprotocol/conformance#523; kept separate from modelcontextprotocol#33 so the two can be discussed and merged independently.
