# 本地一键 Fuzz（默认低内存并发，可通过环境变量覆盖）。
# 用途：封装常用 fuzz 参数，避免每次手工传 FUZZ_WORKERS/FUZZ_JOBS/FUZZ_RSS_LIMIT_MB。
# 默认行为：
#   workers/jobs 默认 2/2（可覆盖）
#   默认 rss_limit_mb=2048（可覆盖）
#   按轮次执行（默认 FUZZ_RUNS=10000000，不走 max_total_time）
#   默认模式 nightly，默认生成覆盖率
# 可覆盖参数：
#   FUZZ_MODE/FUZZ_SKIP_COV/FUZZ_RUNS/FUZZ_TIMEOUT/FUZZ_MAX_LEN
#   FUZZ_WORKERS/FUZZ_JOBS/FUZZ_RSS_LIMIT_MB/FUZZ_MALLOC_LIMIT_MB
# 三个语义宏默认值（可覆盖）：
#   RYANJSON_STRICT_OBJECT_KEY_CHECK=false
#   RYANJSON_DEFAULT_ADD_AT_HEAD=false
#   RYANJSON_SNPRINTF_SUPPORT_SCIENTIFIC=false
