Create a VkPipelineCache at device init, loaded from disk if available. All 65 pipeline creation calls across 19 renderer files now use the shared cache. On shutdown, the cache is serialized to disk so subsequent launches skip redundant shader compilation. Cache path: ~/.local/share/wowee/pipeline_cache.bin (Linux), ~/Library/Caches/wowee/ (macOS), %APPDATA%\wowee\ (Windows). Stale/corrupt caches are handled gracefully (fallback to empty cache).
