Photoshop stores a JPEG thumbnail in image resource 0x040C. PSDParser already had the resource id as a constant but never read it, so `/unpack/preset/thumbnail` had nothing to serve for a PSD. The parser now captures that resource and, when its header says JPEG (format 1), the compressed size fits the resource and the data starts with a JPEG SOI, emits the JPEG behind the 28-byte header as the `THUMBNAIL` embedded document. Anything else is ignored. A thumbnail resource over `maxDataLengthBytes` is skipped instead of failing the parse, so a file that parses today keeps parsing. The raw BGR thumbnail of Photoshop 4.0 (0x0409) is left out. Tests: `testPSD2.psd` and `testPSD_xmp.psd` (both carry 0x040C) emit one JPEG `THUMBNAIL`, `testPSD.psd` (none) emits nothing.
