fix(tmux): pipe M-w copies to the system clipboard via wl-copy

`copy-selection' writes only to tmux's internal paste buffer, so a paste
in any other app got stale content. Switch the M-w binding to
`copy-pipe-no-clear "wl-copy"' (same engine as the existing y binding,
minus the -and-cancel so M-w stays in copy-mode for repeated grabs).
The selection stays visible after copy to make multi-range copying
easier to follow.
