    🔹 Changelog
    Merged upstream improvements from @drakmor

    Major Changes
    • Significant performance optimizations in uelf/fSELF and PFS/NPDRM crypto paths
    • Reduced overhead in crypto hot paths (FPKG, PFS decryption, key scheduling)
    • Improved caching throughout the loader

    Detailed Changes

    Crypto & PFS Optimizations
    • Optimized fpkg crypto hot paths
    • Specialized HMAC-SHA256 for fake-key crypto paths
    • Added request-local virt2phys caches for PFS crypto paths
    • Cached expanded XTS keys per fake-key handle
    • Cached PFS crypto state by key ID
    • Cached NPDRM debug RIF key schedule
    • Switched NPDRM hashing to minimal SHA wrapper
    • Added destructive SHA256 final
    • Dropped per-CPU cache atomics
    • Persisted PFS crypto caches across requests
    • Made PFS crypto cache request-local in ps5-kstuff

    uelf / fSELF Improvements
    • Cached parsed state and streamlined SELF handling
    • Reapplied hardening guards after cache split
    • Cleaned up cmd6 readability in uelf/npdrm
    • Automatic memory allocation for module loading
    • Reuse zero buffer during kernel loads

    Loader & Startup Changes
    • Optimized startup shellcore lookup and CR3 setup
    • Restored legacy shellcore process lookup
    • Optionally disable automatic mounting

    Build & CI Updates
    • Updated GitHub Actions SDK bootstrap
