Claude 78341297a2 Add TIFF (CMYK/Multilayer) and PDF (RGB/CMYK) export formats
- tiff-writer.js: pure-JS multipage TIFF encoder with RGBA and CMYK
  color modes; RGB→CMYK conversion; one IFD per layer for multilayer
- pdf-writer.js: pure-JS PDF-1.4 writer; RGB pages use browser JPEG
  encoding (DCTDecode); CMYK pages embed raw DeviceCMYK pixel data;
  multipage support (one page per visible layer)
- save.js: adds TIFF (CMYK), TIFF (Multilayer), PDF (RGB), PDF (CMYK)
  to the export dialog; CMYK types bypass the separated-layers loop and
  composite with a white background before color conversion
