Apply the generalized image-atomic bounds and backing checks from PR #178. Also reject unsupported descriptor formats before integer fallback and fail unresolved bindless atomics instead of silently deleting them. Rebuild the translator and record chain 467efdfd0b62, with regression tests and findings. Validation: compiler/helper and sanitizer tests, 96 Metal compile/link checks, ten GPU probes, all 28,603 Z-A shaders for Mac and iPhone, and a 240-second Mac station-area run reaching 6,987 frames without a freeze or GPU fault. Reported iPhone cases and the station-to-world transition remain unverified. Co-authored-by: b4f8abbb24dbf56a7d0280f296e16eeb <51352400+b4f8abbb24dbf56a7d0280f296e16eeb@users.noreply.github.com>
