In this lab, you will aggregate resource totals per guild member inside nested objects.

Objective: Fulfill the user stories below and get all the tests to pass to complete the lab.

User Stories:

1. You should accept meal entries shaped like { member, gold, silver, reputation, experience }.
2. You should implement addLootEntry(object, entry) that clones and updates cumulative resources per member.
3. You should implement getMemberTotals(object, member) with guard clauses for unknown members.
4. You should implement listTopMembers(object, key, limit) that sorts descending by a specific resource type (e.g., finding the member with the most gold).
5. You should implement cloneGuildData(object) to protect against accidental mutations.

Note: Use Object.keys, Object.values, and Object.entries. Include tests for aggregation accuracy and cloning behavior.
