JAB-devandClaude Sonnet 5.5 1babc10d42 fix(agc): refuse merged 4_4_4_4 writes from shaders that write memory under late tests ...

A partial 4_4_4_4 write merges inside a pixel shader that declares
early fragment tests. When the guest runs the shader under late tests,
pixels that the depth or stencil test rejects still execute it on the
console, so their buffer and image stores, atomics and GDS operations
happen there. Under forced early tests they would be dropped. Such a
merge now throws, unless the guest asked for early tests itself. The
merged target's own image write does not count.

A recompile test checks two things for a merging shader that adds to a
buffer counter: under late tests it throws, and under the guest's early
tests it compiles with its one atomic add beside the merge. The same
shader without a merge still compiles under late tests.
