How can I completely disable Plasma’s clipboard manager in Cachy OS without breaking normal copy-paste?

I’m using CachyOS (Arch Linux) with KDE Plasma (plasmashell 6.5.2) and want to completely disable the Plasma clipboard manager (klipper).

Even limiting it to a single entry, it interferes with normal copy-paste:

Sometimes pastes older entries instead of the most recent

Middle-click selection occasionally fails

QEMU/KVM clipboard sharing is inconsistent (host → guest works sometimes, guest → host sometimes, sometimes neither)

I want to keep standard Ctrl+C / Ctrl+V copy-paste working while stopping klipper from running or intercepting clipboard operations.

What is the correct way to permanently disable or remove klipper while preserving the native X11/Wayland clipboard?
