  • Add cupti64_2026.1.1.dll to the pathfinder descriptor catalog so load_nvidia_dynamic_lib("cupti") recognizes the DLL shipped with Windows CTK 13.2.1.
  • Add the cuda-pathfinder1.5.3 release notes and version-switcher entry.

Add the CTK 13.2.1 CUPTI DLL name to the descriptor catalog so Windows already-loaded detection recognizes the installed library and the cupti pathfinder test can pass again.
