Nicolas GonzalezandClaude Opus 5.5 0fdd66d900 fix(agc): hold a label read trap until the store and skip aliased memory ...

The trap was released when FlushPending took the image out of the pending
registry, before it waited for GpuMutex, so a read in between saw the old
bytes; cache eviction and explicit write-backs did not release it at all.
Every store now releases it in writeBackLayers: after recording the GPU copy
into the import, or before the first CPU access on the CPU path, which also
releases the traps of other images on the same pages. A trapped image is
stored whole, and direct memory mapped at a second address is not trapped.
