Summary: This is an automated Renovate PR that updates the pinned digest for the postgres:18-alpine image used by the optional postgres-test service in docker-compose.yml (the pluggable Postgres backend from ADR-026, brought up via docker compose --profile postgres up -d postgres-test). Single line changed:

-    image: docker.io/library/postgres:18-alpine@sha256:a1d02e4bd40c94d3bf2bdd3678c137388e76d9efcd23c285e9429d336a834b44
+    image: docker.io/library/postgres:18-alpine@sha256:d3e1620b530c944afa6e887d22eb899824da68e19c52024bf98f5220c88a65b2

Findings:

• Both digests are well-formed 64-hex-char SHA-256 values, and the tag (18-alpine) is unchanged — this is a same-tag digest refresh, not a version bump, so no behavioral/API surface change is expected.
• The change is scoped to a single, non-default, test-only service profile (postgres) — no impact on the default stack or production paths.
• No source code, tests, or CI workflows are touched, so the CLAUDE.md testing/API-surface/annotation gates don't apply here.
• SonarCloud Quality Gate already passed with 0 new issues.

No concerns — this is a safe, mechanical digest pin update. Good to merge once CI is green.
