feat: copy the output panel to the system clipboard (#11)

New app-level `copy` / `copy all` / `copy last` command (ADR-0041). Delivery is OSC 52 *and* a best-effort native write (arboard), always both — OSC 52 acceptance is undetectable, so a true fallback can't be built. Payload is the panel's plain text exactly as rendered (tags, ✓/✗, box-drawing), drift-locked to render_output_line. arboard added --no-default-features (X11-only; OSC 52 covers Wayland). Amends ADR-0003's command registry; requirements V6.
