arboard (image-data) approved for clipboard paste: image bytes become a PNG attachment, copied files inside the vault are linked without copying, outside files are copied; works in Visual and Source. image crate gains jpeg, gif, webp, bmp decoders. Lazy system-font fallbacks for 28 scripts (Bengali, Indic, Thai, CJK, Khmer...) and the math font as last resort. JetBrains Mono copy with calt emptied (SIL OFL, renamed). Big embedded images are shrunk to the texture limit off the UI thread (fixes a crash). Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
