battleblob1andClaude Opus 5.5 9b84f9d5a1 fix(recompiler): replay stencil exports of pixel shaders that only read through BDA ...

StencilReplaySafe refused every program with usesDma, including pixel
shaders whose only BDA accesses are reads (Onimusha: Way of the Sword,
PPSA27836: one global load, then image and buffer reads). Replaying such
a shader per reference value is idempotent: its only side effect is the
first-fault record, a compare-exchange that keeps the first fault; a
fault is never retried but thrown by CheckFault, and replayed draws with
a BDA table already wait and check faults before publishing. Written-page
tracking exists only in programs with bdaWrites, which stay refused.

Compiled shaders now carry bdaWrites, and ShadersWriteMemory counts a BDA
page table as a memory write only for a program that writes through it.
