X Title: Reorganize graph tests and add device-side launch support by Andy-Jost · Pull Request #1512 · NVIDIA/cuda-python

Description: Summary This PR reorganizes the graph tests into a new tests/graph/ subdirectory, adds a public Graph.handle property, and introduces tests for device-side graph launch. Closes #1331 Changes Test Reorganization Create new tests/graph/ subdirectory following the pattern of tests/memory_ipc/ Break apart test_graph.py into logical groupings: test_basic.py: basic graph construction and topology tests test_conditional.py: conditional node tests (if, if-else, switch, while) test_advanced.py: child graphs, update, stream lifetime test_options.py: debug print, complete options, build mode Incorporate test_graph_mem.py (renamed to test_capture_alloc.py) Add shared kernel compilation helpers in tests/helpers/graph_kernels.py API Addition Add Graph.handle property to expose the underlying CUgraphExec handle Follows the existing pattern of Stream.handle and Event.handle Forward-compatible with future RAII handle refactoring Device-Side Graph Launch Tests Add test_device_launch.py with tests for device-side graph launch Uses cudaGraphLaunch() from device code via cudaStreamGraphTailLaunch Requires Hopper (sm_90+) architecture Uses cuda.pathfinder.find_nvidia_header_directory() to locate libcudadevrt.a Test Coverage 58 tests total in tests/graph/ All tests pass on Hopper (H200) Device launch tests skip on pre-Hopper architectures
