nurikit

Configure, build, and run the `fuzzer` (libFuzzer + ASan/UBSan) CMake variant of nurikit, then triage crashes and report coverage. Use when asked to fuzz-test a format parser (cif, mol2, pdb, sdf, smi), investigate a fuzz crash, or run the build/fuzz/triage/report loop. Clang-only; all fuzz output lives in a user-chosen directory outside git.

Configure and build the `sanitizer` (ASan/UBSan) CMake preset of nurikit. Use when building, configuring, or running the sanitizer build — or when a sanitizer build fails to link/run under GCC. Covers the clang++ requirement (active GCC bug), the preset, and the build-time environment variables.
