Mulciber desktop OS layer

mulciber-platform is the experimental desktop OS layer of the Mulciber native game-development stack. It owns native application connections, windows, event pumping, drawable metrics, and borrowed graphics surface targets without imposing a cross-platform windowing framework.

Version 0.2.0 contains peer native AppKit, Win32, Wayland, and X11 implementations exercised by Mulciber's Metal and Vulkan probes. New in this version, the event pump takes a fallible handler and returns the first application error once native dispatch completes (a breaking change from 0.1), and the platform owns the startup wait for first drawable metrics. Input, display enumeration, multi-window support, and a stable application-facing API remain in progress. The current API is research-stage and may change without compatibility guarantees. On docs.rs, use the target selector to view the implementation available for each operating system.

Development, design contracts, runnable probes, and recorded validation evidence live in the Mulciber repository.
