Major architectural update to graphics/material/shader system: - Introduced strongly-typed key structs (Key64/Key128) for passes, variants, and pipelines; removed legacy key types. - Implemented robust hashing and key generation utilities for efficient variant and pipeline lookup/caching. - Shader compiler now compiles/caches all keyword variants using new key system; includes handled as lists. - Switched to push constant root signature for per-draw data; updated HLSL and C# codegen accordingly. - Refactored Material, Shader, and Pass data structures for cache efficiency and variant support. - Pipeline library and PSO management now use 128-bit keys and variant-specific caching. - Replaced WorldNode with SceneNode in editor/scene graph; introduced ComponentManager for archetype/query management. - Migrated math utilities to Misaki.HighPerformance.Mathematics; updated editor controls. - Updated all HLSL and codegen for new buffer/push constant layouts and macros. - Misc: project reference cleanup, D3D12 Work Graph support, doc updates, and code modernization.
