TODO: Bump ArgoCD Image Updater memory limit to 512Mi

What: ArgoCD Image Updater OOM'd at 256Mi limit (currently using 218Mi). Bump to 512Mi.

Where: pal-e-services/terraform/main.tf line 241 — change limits = { memory = "256Mi" } to 512Mi.

Why: Firing OOMKilled critical alert. Image updater scans all Harbor repos for new tags. More services = more memory. At 218/256Mi it's one spike away from another OOM.

Apply: Manual tofu apply in pal-e-services (no CI pipeline). Requires -lock=false if run from agent prompt.

Alert: OOMKilled critical — will auto-clear after pod runs without OOM for the alert's for duration.
