[BUG]: Replace obsolete Nsight GUI utility names with nsys-ui and ncu-ui

[isVoid]

Problem

cuda.pathfinder.SUPPORTED_BINARY_UTILITIES currently includes the legacy GUI names nsight-sys and nsight-compute, but omits the executable names used by supported Nsight releases: nsys-ui and ncu-ui.

Because find_nvidia_binary_utility() treats the requested name literally (and appends .exe on Windows), calls using the legacy names return None on a current standalone Nsight installation even though the corresponding GUI is installed.

The CLI entries nsys and ncu are correct and should remain unchanged.

Evidence

• Current supported-name table:
  https://github.com/NVIDIA/cuda-python/blob/main/cuda_pathfinder/cuda/pathfinder/_binaries/supported_nvidia_binaries.py
• Current lookup implementation:
  https://github.com/NVIDIA/cuda-python/blob/main/cuda_pathfinder/cuda/pathfinder/_binaries/find_nvidia_binary_utility.py
• Nsight Systems documents the GUI executable as nsys-ui:
  https://docs.nvidia.com/nsight-systems/InstallationGuide/index.html#launching-the-gui
• Nsight Compute documents the GUI executable as ncu-ui:
  https://docs.nvidia.com/nsight-compute/NsightCompute/index.html#quickstart
• The last confirmed Windows package containing nsight-sys.exe was Nsight Systems 2020.3.4.32, bundled with CUDA Toolkit 11.1:
  https://developer.download.nvidia.com/compute/cuda/repos/windows/x86_64/version_11.1.0.json

These legacy names predate the CUDA Toolkit majors currently covered by cuda.pathfinder's “two most recent major versions” support policy.

Proposed change

1. Replace nsight-sys with nsys-ui and nsight-compute with ncu-ui in the supported binary descriptors.
2. Preserve nsys and ncu as the CLI utility names.
3. Add standalone Windows discovery through the existing Nsight registry roots:
   • Nsight Systems: locate nsys-ui.exe under the host directory (for example, host-windows-x64).
   • Nsight Compute: locate the root shortcut and/or the actual executable under host/windows-desktop-*/ncu-ui.exe.
4. Add tests for wheel/Conda layouts and standalone Windows layouts.

If removing names from the public supported tuple is considered too disruptive, a compatibility alternative is to retain the old inputs temporarily as deprecated aliases that resolve to the current UI executable, while documenting that the returned basename differs.

Expected behavior

find_nvidia_binary_utility("nsys-ui")  # absolute path to nsys-ui[.exe]
find_nvidia_binary_utility("ncu-ui")   # absolute path to ncu-ui[.exe]
find_nvidia_binary_utility("nsys")     # unchanged
find_nvidia_binary_utility("ncu")      # unchanged
