bflatasticandClaude Opus 5.5 a1a5c79b03 M3.73: blend modes follow the reference formulas on screen, in SVG and in PDF ...

color::blend gains blend_rgb (the 16 blend functions, with the 0.3/0.59/0.11
luminance of the non-separable modes), composite (source-over with blending)
and the shared opacity-mask luminance weights. Exported SVG masks take
luminance from sRGB values (color-interpolation="sRGB"), as the canvas does.

Tests: a per-mode table on the canvas (object, fill and group blend modes,
within 1/255; Exclusion 2/255 in the rasteriser's 8-bit pipeline), the same
table through SVG export rendered by resvg, clip and invert masks against the
canvas, and every mode's PDF name read back.

Cargo.toml

Rename DrawCraft → VectorCraft: crates (vectorcraft-*), apps, binaries, types, env vars, docs, examples (.vectorcraft); old .drawcraft files and preferences still load. Fix: text bounds exact after opening a file; selection no longer marks a document modified (dirty = content differs from the saved document). Screenshots and renders regenerated.
