C0NT41N3R L04D on the SYST3M tab + GET /api/container-resources.
Backend (hive-c0re/src/container_stats.rs): reads cgroup v2 cpu.stat +
memory.{current,peak,max} for each running agent machine
(machine-h\x2d<name>.scope under machine.slice), read-only/world-
readable so no hive-priv. CPU is a two-sample (~200ms) host-normalised
percentage; one shared sleep covers all agents. Skips agents whose
scope dir is absent (= not running). Network omitted: agents share the
host netns, no per-container counter.
Frontend: a polled C0NT41N3R L04D table on SYST3M (agent / cpu / mem /
peak / limit with meter bars), reusing the ST4TS table style. Polls
/api/container-resources every 5s only while the tab is active.
Backend reviewed-in-principle by damocles (path escaping + cpu delta
math); ping for the on-host sign-off.
