…it and OOM-kill count, plus summed process RSS s19-compaction-g3-20261010b: island 0 got SIGTERM mid critic training and the host-memory samples had cgroup_current/peak = null (only /sys/fs/cgroup root was read), so a memory cause could not be checked. The sampler now resolves the own cgroup from /proc/self/cgroup, reads v2 memory.current/peak/max/events (oom, oom_kill) or v1 usage/max_usage/limit/oom_control, and records the summed VmRSS of all visible processes as a cgroup-free fallback.

背景
s19-compaction-g3-20261010b：岛 0 在 critic 训练中途收到外部 SIGTERM。hostmem 采样的 cgroup_current/peak 一直是 null，因为只读了 /sys/fs/cgroup 根目录，所以无法排除内存原因。
改动（只改观测，不改逻辑）

子 agent 代拍板：观测改动，C 跑用本分支代码（main b31e964 + 本 PR）。
