On 11-02 open sessions plus test runs filled RAM and the 4 GB swap on a
slow disk; the box hung until a hard reset. Member panes now start at
nice 10, IO priority 7 and oom_score_adj 500 with Vitest capped at 2
workers by default, and the system unit caps its cgroup (server + every
pane) at 85% of RAM with 1G swap and OOMPolicy=continue, so the kernel
kills the biggest pane process instead of hanging the machine. Needs
`agenthub server install-system` once.
