Critical fixes: - Add missing #include <string.h> to 5 fuzz targets (wouldn't compile with GCC14+/Clang16+) - Fix fuzz_metadata_from_buf.c OOB read: guard size >= sizeof(int) + FILE_METADATA_WIRE_SIZE - Add Clang compiler check for ENABLE_FUZZ in CMakeLists.txt (fail fast at configure time) - Add fuzz-build CI job (install clang, build all 6 fuzz targets with ENABLE_FUZZ=ON) Warning fixes: - Add UBSan to sanitizer CI matrix (address + undefined) - Remove tautological test_property_glob_consistency (pure/deterministic function) - Use fixed seed srand(42) instead of srand(time(NULL)) for reproducible property tests - Add valid-header + truncated-instructions delta robustness test (exercises instruction-loop error paths) - Fix lcov --remove to exclude '*/_deps/*' (xxhash coverage pollution) - Add comment explaining FASTSYNC_UNDER_VALGRIND skip in test_file.c - Update .gitignore for build-*/ directories
