The desktop app polled full clipboard contents every second on the AWT
event thread to update ChatModel.clipboardHasText. On X11, each read
blocks up to sun.awt.datatransfer.timeout (10s) when the selection owner
does not respond (e.g. after KeePassXC's clipboard auto-clear), making
every click/scroll wait ~9s. clipboardHasText has had no readers since
its only consumer was removed in #4398, so the whole mechanism (desktop
poll, Android clip listener, onResume refresh, expect/actual, state
field) is deleted. See plans/2026-07-11-fix-desktop-clipboard-freeze.md.
* desktop: pick a free port for the call server if 50395 is in use
startServer() bound a hard-coded port (50395); when it was already in use,
NanoWSD threw "BindException: Address already in use: bind" and the call
failed. It now falls back to an OS-assigned free port, and WebRTCController
opens the browser at the actually-bound port (server.listeningPort) -- still
50395 in the normal case, so browser camera/mic permission stays put.
* plans: justify call server port-bind fix
