## Summary - Adds `LimitNOFILE=65536` to both web and worker systemd service units - Fixes recurring `Errno::EMFILE` (Too many open files) errors during peak traffic after deploys ## Context Puma workers idle at 720-770 open FDs against the default soft limit of 1024, leaving ~250 FDs of headroom. During deploy-triggered instance refreshes at peak traffic, concurrent requests exhaust the remaining FDs, causing EMFILE across all web instances. 3 incidents in March 2026 with escalating event counts. The hard limit is already 524288, so this just raises the soft limit to a standard production value. Self-hosted instances pick this up automatically via `cwctl --upgrade`.
