巡检 camoufox-bin 进程数，防止泄漏堆积撑爆内存死机。
背景
camoufox-bin（反指纹 Firefox）进程泄漏堆积是本机反复 OOM 死机的元凶（07-17/07-27/07-29 三次）。 根因是 browser.ts close() 不退 daemon 致 camoufox-bin 孤儿化，7.1 未根治。本技能是兜底安全网： 心跳里检测堆积，超阈值告警，超硬限杀超龄孤儿，避免再 OOM。
用法
bash ./skills/camoufox-guard/scripts/guard.sh由 it-engineer HEARTBEAT 定期调用。输出：
- 正常：
camoufox-guard: OK (N 个 camoufox-bin，阈值 6) - 告警：
⚠️ camoufox-bin = N+ 进程详情（pid/年龄/内存） - 清理：
🔴 超硬限，清理 X 个超 30min 的孤儿+ kill 记录
阈值（环境变量可覆盖）
| 变量 | 默认 | 含义 |
|---|---|---|
CAMOUFOX_GUARD_THRESHOLD | 6 | 告警阈值（并发上限） |
CAMOUFOX_GUARD_HARD_LIMIT | 12 | 硬上限（超了杀最老孤儿） |
CAMOUFOX_GUARD_MAX_AGE_MIN | 30 | 超此年龄(分钟)视为孤儿可杀 |
安全保证
只杀 age > 30min 的 camoufox-bin。活跃浏览器任务（发布/抓取，通常 < 30min）不受影响。 若清理后仍超硬限（孤儿非超龄），脚本建议重启 gateway。
