Sessions inside tmux used to skip the clipboard provider entirely, so
yanks only reached the machine's own Wayland clipboard and never
traveled over OSC 52 to clients attached via SSH. Now every copy also
emits OSC 52, which tmux turns into a buffer and rebroadcasts to all
attached clients. Paste prefers wl-paste when a display is available.
This also drops the private-file fallback clipboard and its regtype
sidecar: Neovim's built-in clipboard layer already restores the register
type when pasted content matches its cache, and OSC 52 queries answered
by tmux cover the display-less paste case.
