Static Analysis

All checks pass:

• go build ./... — clean
• go vet ./... — clean
• go mod tidy — no drift

Review Summary

LGTM — This is a straightforward patch-level version bump of the MongoDB image used for the local test replica set (mongo/Dockerfile), from 5.0.32 → 5.0.33. The change is minimal and low-risk:

• Single line changed in mongo/Dockerfile
• Stays within the 5.0.x patch series (no breaking changes expected)
• The Dockerfile structure (WORKDIR, COPY, HEALTHCHECK, CMD) is unchanged
• Used only in docker-compose.yml for local integration tests, so no production impact

No issues found. Nice clean dependency bump.
