* working on an in-memory store for screen information
* nostrpos sentinel
* textareainput now tracks selection (to update backend)
* make websocket connections much safer. add a defer/panic handler for each ws message handled on backend. don't allow client to reconnect to backend ws handler more than once per second (handles issue with lots of fast fails)
* use onSelect to have frontend textarea sync state to backend ScreenMem store
* restore cmdline when switching screens
* prettier
