* craft-psd: Photoshop PSD/PSB reader and writer, moved from PhotoCraft PhotoCraft's `photocraft-psd` crate (crates/psd at storytold/photocraft 63b641b55e54bf8f5c83efd977fdb16a2c255431) as `craft-psd`: the lossless PSD/PSB model, reader, writer and builder, descriptors, the Photoshop resource files that share its primitives (.abr, .asl, .aco, .act, .ase, .grd, .pat, .atn, .csh, .shc) and the Photoshop blocks of a layered TIFF. The crate had no dependency on any other PhotoCraft crate. Code is unchanged apart from the crate name, craft-libs' rustfmt width, comments that named other PhotoCraft crates, issue references (now `photocraft#N`), and the corpus tests' directory (`CRAFT_PSD_CORPUS` or `corpus/` at the workspace root). Tests, proptests, fuzz targets and fixtures move with it. Part of #778, #786. * craft-psd: engine_data, the text engine document of type layers The EngineData reader and writer from PhotoCraft's photocraft-text (crates/text/src/engine_data.rs at storytold/photocraft 63b641b5): a tree of values that is written back in Photoshop's layout, with strings stored as plain bytes kept as plain bytes. From EffectCraft's effectcraft-psd (crates/psd/src/engine_data.rs at storytold/effectcraft 072e1af9), ported onto that tree: `first_style`, the first style run as a typed `TextStyle` with bounded sizes and spacings, and `minimal`, a one-run document for writers and fixtures. `Value::index` is new. Both apps had their own parser for the same syntax. * craft-psd: engine_data::parse_lossy reads what it can of a damaged document EffectCraft's EngineData reader was best effort: a truncated or damaged document still gave the text and style it held. `parse_lossy` does that on the same parser: a truncated dictionary, array or string keeps what it has, a byte that starts no key is skipped, a token that is no number becomes a name, and garbage gives an empty dictionary. `parse` stays strict and is unchanged in what it accepts. The parser's `value` is split into one function per kind of value, and reads with `get` instead of indexing.
