bug: uri is not being checked for resources

[JosiahParry]

When using a resource with claude code mcpr is causing an error right here:

mcpr/R/methods.R

Lines 227 to 233 in b734565

	if (is.null(params$name) || !is.character(params$name)) {
	return(create_error(
	JSONRPC_INVALID_PARAMS,
	"Missing or invalid resource name",
	id = id
	))
	}

claude only sends the URI and not the name
