Subject: [PATCH] chore: raise service heap limit to 1.5GB

512MB was too small for per-session DevTools/Lighthouse state under
concurrent agents, causing JavaScript heap OOM crashes that dropped every
session mid-task (see #33). Raise --max-old-space-size to 1536 in both the
launchd plist and systemd service templates.
