Subject: [PATCH] feat: add option to copy using osc52

Add `oscClipboard` config option to enable OSC 52 clipboard support
for headless/remote machines where traditional clipboard access isn't
available.

When enabled, the copy number (y) and copy url (Y) keybindings will
use OSC 52 escape sequences instead of the system clipboard. This
allows clipboard content to be forwarded to the local machine via
terminal multiplexers like tmux or screen.

Fixes #559
