Replace the external clipboard dependency with small macOS, Windows, and X11 helpers and integrate them into coding-agent. Run native clipboard operations on worker threads and make command fallbacks asynchronous. Preserve incremental X11 transfers, legacy text encodings, native image formats, and existing Wayland and platform tools. Include native prebuilds with ARM64 page alignment, packaging updates, and regression coverage.
