## Executive Summary
Fixes fixed Steam Overlay coexistence due to Vulkan layer procaddr/trampolining issues fixed dx_api always showing dx? for DX9/11, also added DX3-7 fixed imgui static library being installed unexpectedly vulkan: removed redundant instance dispatch table reload vulkan: fixed loader procaddr forwarding vulkan: exported Vulkan layer negotiation entrypoint Contributors @Billli11

## Architectural & Systems Analysis
From a graphics pipeline, kernel sub-system, and runtime compatibility perspective:

- **Translation Efficiency:** Minimizing DirectX/Vulkan mapping overhead (DXVK, VKD3D-Proton) delivers deterministic frame times.
- **Kernel Synchronization:** Integration of wineserver optimizations with fsync/futex primitives eradicates multi-threaded bottlenecks.
- **Engine Neutrality:** Open engines like Godot provide a genuinely vendor-independent development target.

## Impact on the Open Ecosystem
Solidifies Linux as an uncompromising, tier-one operating system for high-performance interactive 3D computing.
