Decode lossless CRX and version 0x100/0x200 C-RAW in portable Rust, including sensor geometry, timed white balance and black/white levels. Verify all sensor samples against six independent M50/R100/R8 references. Any CR3 decode error falls back to the embedded JPEG, as CR3 files did before this decoder. The full sensor buffer is allocated only after the first plane decodes, and plane buffers grow row by row. Tile planes decode in parallel with a windowed bit reader (24 MP: 424 -> 89 ms lossless, 519 -> 138 ms C-RAW on an M4). Add guarded CR3 camera-JPEG colour fitting with independent framing validation, relative white balance and cache invalidation. Validation: cargo xtask ci.
