breadclip: add --screenshot CLI mode for automated capture

Same pattern as breadbar/breadbox: render the clipboard-history panel,
capture it via bread-screenshots, then exit. One view ("history"), full
known-size canvas capture since the panel isn't its own layer surface.

active_window()/focused_monitor() (used to anchor the panel next to the
real focused window) both resolve to None inside bread-capture's isolated
environment (HYPRLAND_INSTANCE_SIGNATURE is deliberately unset there), so
the panel falls back to its already-existing centered layout — exactly
the deterministic behavior a screenshot needs, with no screenshot-mode-
specific positioning logic required.

Also fixes the same singleton footgun as breadbox: toggle_or_kill()
kills whatever's holding breadclip's single-instance lock, which is
typically the real running instance. A screenshot run now skips it
entirely instead of fighting over (and killing) the operator's real
clipboard panel.
