Figma needs derivedTextData (layoutSize, fontMetaData with font digest) and textUserLayoutVersion to render text in .fig files. Without these fields, text nodes appear as empty boxes when opened in Figma. - Add DerivedTextData message to kiwi schema (field 359) - Add derivedTextData and textUserLayoutVersion to NodeChange codec - Compute SHA-1 font digests from loaded font binaries at export time - Emit textData.lines with lineType: PLAIN for each paragraph - Expose getLoadedFontData() from fonts module for digest computation Closes #64
