DNG export gains a "Lossy" compression: the raw data is demosaiced to linear camera RGB (OpcodeList3 and the default crop applied), scaled to the resize long edge when one is set, and stored as 8-bit baseline JPEG tiles at the export quality. The codes follow a 1/2.2 power curve that a LinearizationTable maps back to linear 16-bit values; colour matrices, white balance and the profile look are kept. Available in the export dialog, `app.export` (`dngCompression: "lossy"`) and the MCP export tool. Also fixes a new clippy lint (chunks_exact_to_as_chunks) in pipeline/spots.rs that fails `cargo xtask ci` on Rust 1.99. Sources: Adobe DNG Specification 1.4+ (Compression 34892, LinearizationTable); own design for the code curve. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
