- Add hdr.rs with HdrTarget (Rgba16Float render target) and HDR_FORMAT constant - Add bloom.rs with BloomResources (5-level mip chain), BloomUniform, and mip_sizes() - Add tonemap.rs with TonemapUniform and CPU-side aces_tonemap() for testing - Export all new types from lib.rs - 33 tests passing (26 existing + 3 bloom + 4 tonemap) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
