JavaScript port decodes YAPF 2; VS Code and Figma open every file

Browse source 
yapf.js: decodeTexture (container, yapf-sum checks, code books with
context decoding, 16-bit / float planes, GPU block tiles), BC1-BC7 /
BC6H block decoding and textureToRGBA for display. Matches the C library
on 417 generated files (surfaces bit-exact) and survives fuzzing with
clean YapfErrors; fixtures in bindings/js/test-data keep it checked.

VS Code preview: pickers for mip, face, layer, frame and slice; storage,
normal-map convention and version in the info bar. Figma import:
textures converted to 8-bit, 8-bit images stay exact.
