/**
 * Issue #2939 — random OOM in Docker. The standalone launcher
 * (`scripts/dev/run-standalone.mjs`, the Docker CMD) must honor
 * OMNIROUTE_MEMORY_MB instead of relying only on the image-level NODE_OPTIONS
 * fallback, so Docker users can raise the server heap under load / large
 * SQLite DBs.
 *
 * `resolveMaxOldSpaceMb` is the shared heap-ceiling resolver the launcher now
 * uses (mirroring `omniroute serve`): OMNIROUTE_MEMORY_MB clamped to [64, 16384],
 * default 512.
