Keep Service Memory Lean

Use when a service OOMs / its tasks restart after a PR that added a dependency, when memory-tight replicas (small containers — e.g. 512MB/1GB) die under load or on deploy, or whenever the proposed fix for memory pressure is "just give it more RAM". Also use proactively when ADDING a heavy or optional library (cloud/vendor SDK, PDF/image/ML/crypto lib) to a long-running service. The discipline: keep per-process RSS lean by lazy-loading cold-path dependencies, and treat a memory regression as a code smell to hunt — not a reason to upsize the host. Covers the reservation-vs-actual-RSS + deploy-2x-surge mechanism that turns a small boot-memory regression into a full OOM outage. Principle-first; Node/ESM examples, ports to any language/orchestrator.
