Subject: [PATCH] fix: make yank-to-system-clipboard work when the document
 isn't focused

`navigator.clipboard.writeText` rejects with "Document is not focused"
during focus changes, so with `set clipboard=unnamed` a yank silently
never reaches the system clipboard and the setting appears to stop working
(intermittently). The clipboard->yank read path already guards against this
exact error, but the yank->clipboard write path did not, and an
unhandled rejection also dropped the state update.

Prefer Electron's synchronous, focus-independent clipboard on the desktop
app, falling back to the async API where `require` is unavailable (e.g.
mobile). On any failure, leave `lastYankBuffer` unchanged so a later
keyup/click/focusin event retries the write.
