• Added ApplicationInstanceResolver interface and its implementation in the auto‐generated GraphQL resolver file.
• Extended GraphQL schema definitions for ApplicationInstance and InstanceUtilization types.
• Added or updated query functions and resolvers to calculate CPU/memory usage for instances.

• [nitpick] Verify that the order of arguments (teamSlug, workloadName, instanceName) correctly matches the expected placeholders (namespace, container, pod) in the usage query string for clarity.

current, err := c.query(ctx, env, fmt.Sprintf(usageQ, teamSlug, workloadName, instanceName))

• [nitpick] Consider adding tests for the new ApplicationInstance.InstanceUtilization resolver to ensure correct behavior and error handling across various scenarios.

Consider adding a type check or error handling before the type assertion on args["resourceType"] to prevent a potential panic if the argument value is not of the expected type.
