In general, to convey poetic line breaks in "continuous text", replace the line break with a slash. "I've never seen a purple cow./I never hope to see one./But I can tell you anyhow,/I'd rather see than be one." I don't use Twitter so I can't say if this convention is commonly used there, but it's the normal convention in other contexts.
If you hold down the Shift key and press Enter it adds a line break. Apparently it won't work in some clients, but I just tried it on a tweet and it seems to work.
