Add DLSS accuracy mode and GLIBC 2.41 release builds

- Add default-off PreferAccuracy for all native kernel families,
  including RDNA4 FP8 variants.

- Restore intermediate FP8 quantization, per-MMA FP16 rounding,
  denormal handling and NGX synchronization in accuracy mode.

- Select separately marked accuracy kernels and use a separate JIT
  cache; reject mixed sets and never silently substitute fast kernels.

- Add a pinned GLIBC 2.41 build environment for ZLUDA/LLVM, the DLLs
  and both kernel sets, with ABI checks and toolchain provenance.

- Support parallel target builds and pre-extracted PTX; correct
  ROCm header paths and Clang-CL input handling.

- Bump to 0.1.3 and update release notes, documentation and tests.

Validation: 11 tests passed; all 912 kernels built; E/K/M GPU harness
runs completed with accuracy off/on. Packaged libraries loaded under
GLIBC 2.41 and require no GLIBC version newer than 2.38.

RTX image-quality parity remains unverified.
