Need to add parameters to Tool generation for arguments

[erikist]

Currently, tool generation is not adding in the parameters for a given request in the following generation function:

func generateMCPTool(g *protogen.GeneratedFile, method *protogen.Method, mcpServerName string)

currently this function is outputting things like:

func (s *vibeServiceMCPServer) SetVibeTool() mcp.Tool {
	tool := mcp.NewTool("SetVibe", mcp.WithDescription("Set the Vibe"))
	return tool
}

This should handle the parameters of the input to the RCP, in this case, something like this should be output:

func (s *vibeServiceMCPServer) SetVibeTool() mcp.Tool {
	tool := mcp.NewTool(
		"SetVibe", mcp.WithDescription("Set the Vibe"),
		mcp.WithString(
			"vibe",
			mcp.Required(),
			mcp.Description("The vibe to set on the server"),
		),
	)
	return tool
}
