In this example: MCP url: https://foo.com/mcp WWW-Auth resource_metadata: https://foo.com/laugh/in/the/face/of/conventions.json PRM: https://foo.com/laugh/in/the/face/of/conventions.json PRM resource property: https://foo.com/mcp I use to do: a URL derived from "WWW-Auth resource_metadata" (which is actually just PRM) is compared to "PRM resource property" but instead it should be: "MCP url" compared to "PRM resource property" Which is what this PR addresses

In this example:
MCP url: https://foo.com/mcp
WWW-Auth resource_metadata: https://foo.com/laugh/in/the/face/of/conventions.json
PRM: https://foo.com/laugh/in/the/face/of/conventions.json
PRM resource property: https://foo.com/mcp
I use to do:
a URL derived from "WWW-Auth resource_metadata" (which is actually just PRM) is compared to "PRM resource property"
but instead it should be:
"MCP url" compared to "PRM resource property"
