KenM76andClaude Opus 5.5 ea6d0c6bfb M12: pdfcraft-prc-render, a headless renderer for PRC models ...

New L3 crate over pdfcraft-prc: assemble places every product-tree
tessellation into world space with its colours (pure `place` does the
transform), Camera fits a view to the model, and render fills
depth-buffered triangles with headlight or unlit shading into an RGBA
image. Opaque triangles draw first, translucent ones blend over them;
perspective views clip at a near plane.

Never panics: MAX_RENDER_PIXELS and MAX_ASSEMBLED_TRIANGLES cap the
work, every pixel and vertex index is checked, and damage returns
RenderError. Single-threaded.

Tests: 24 unit tests (two drive the product-tree placement path) plus an end-to-end one that builds a synthetic
PRC stream in-test, renders it, and checks the background, the nearer
triangle and the farther one by pixel; every truncation of that stream
parses and assembles without panicking. Reverting the depth test or the
placement transform fails the matching tests.

Adapted from pdfcer (MIT, same author) at 912437c3, trimmed to
the camera, raster and headlight parts and rewritten to the
pdfcraft-prc types.
