Feature: support Wayland clipboard on Linux

[life00]

X11 xclip is imcompatible with Wayland. Please add support for Wayland clipboard on Linux.

wl-clipboard is the standard Wayland approach for clipboard.

wl-copy and wl-paste commands are used to copy and paste.

thanks :)

I hit this same issue but found the issue was actually in opencode.
It already uses wl-copy but wl-paste is broken.

Opened a PR with a fix: anomalyco/opencode#29881

@life00 @zackslash you are both right :)
i now merged #41 which adds wl-copy on the vimcode side, so yanks will hit the system clipboard on Wayland. however like @zackslash mentioned opencode has a bug that pasting is not supported on wayland, which means that pasting will still be broken until opencode fixes it.
