AMDBTX v1.2.2 — SHA-256 packing + 3% NPS, Windows PATH fix, bundle-priority fix

Changes

  • SHA-256 oracle index packing: rewrote d_candidate_from_midstate index-bytes packing in solver/src/matmul_kernel.hip from d_set_sha_byte OR-equals loop to direct d_bswap32(index) stores. +3% NPS at batch=524288, +1.3% at batch=131072. Consensus preserved (35137 gate passes, 0 verify_misses).
  • Windows subprocess DLL search fix (src/amdbtx_miner/gbt_solve_wrapper.py):
    The 6800M laptop hit STATUS_DLL_NOT_FOUND (0xC0000135) because spawned solver could not find bundled HIP runtime DLLs. Fixed by prepending the bundle's runtime/ directory to the spawned solver's PATH env var on Windows (and LD_LIBRARY_PATH on Linux). Now bundled ROCm runtime DLLs/.so are findable without separate HIP SDK install.
  • Linux Runpath fix (solver/CMakeLists.txt): solves portable-Linux No HIP GPU found errors by embedding $ORIGIN:$ORIGIN/runtime in solver RUNPATH. Bundled PyInstaller runtime/*.so files are now found without system ROCm install.
  • resolve_solver_path bundle-priority fix (src/amdbtx_miner/__main__.py): PyInstaller bundle (sys._MEIPASS) is now checked before the gbt_solve_path set in config.yaml. Users who had a stale path in config can now use the bundled single-file EXE without editing config. (Regression test: tests/test_resolve_solver_path.py.)
  • Robust packaging scripts: package_linux.sh and build_and_package_windows.ps1 now auto-discover ROCm SDK location (no hard-coded Python 3.12 / MSVC 14.44 / /opt/rocm-7.2.* paths) so the same code builds on Ubuntu 22/20, HiveOS, and any ROCm 6.x/7.x install.
