Modifications and build

0001-psromfs-uncompressed-no-cjk-fallback-font.patch: changes the build makefile psi/psromfs.mak so PostScript resources are stored uncompressed and the DroidSansFallback CJK font is omitted.
0002-pcl-kcmy-simple-color-default-palette.patch: fixes pcl/pcl/pcindxed.c so PCL 3 color jobs using KCMY simple color mode keep their yellow, red and green instead of printing them black, and removes a one-byte write past the palette.
build.sh: the exact build script (Emscripten 6.0.9, -Oz, pdfwrite device only, pinned SOURCE_DATE_EPOCH).
BUILD.md: toolchain, configure flags and rebuild instructions.
SHA256SUMS of the served engine files and the engine notice.

This website: complete source

pcl-to-pdf-site-source.tar.gz (SHA-256): the application, the shared site code, workspace configuration and lockfile, and the exact third-party source files bundled into the site's JavaScript. Generated at build time.
Rebuild with pnpm install --frozen-lockfile, then pnpm --filter @foundry/pcl-to-pdf build, after placing the GhostPDL tarball parts in apps/pcl-to-pdf/source-archive/ghostpdl/ and building the engine with build.sh.
