fix(clipper): remove dead wlCopyProc reference causing ReferenceError on teardown (v2.4.2)

Component.onDestruction in Main.qml referenced wlCopyProc, an id that
does not exist in this file. It threw:

  ReferenceError: wlCopyProc is not defined

on panel/shell teardown. The id was left over from an earlier refactor;
wl-copy usage already lives in copyToClipboardProc and direct
Quickshell.execDetached(["wl-copy", ...]) calls, so no replacement
logic is needed — just delete the two dead lines.

Bumps version to 2.4.2 and adds a matching CHANGELOG entry.

+- Removed a dead `wlCopyProc` reference in `Component.onDestruction` (`Main.qml`) that threw `ReferenceError: wlCopyProc is not defined` when the panel or shell was torn down. The id was left over from an earlier refactor; wl-copy usage already lives in `copyToClipboardProc` and direct `Quickshell.execDetached(["wl-copy", ...])` calls, so no replacement logic is needed.
