Quick Summary
Balance overlapping key ranges across distributed shards while enforcing a maximum overlap limit.
Shift shard boundaries to resolve conflicts, drop eclipsed shards, and fill gaps for continuous coverage.
Apply a greedy sweep-line approach processing shards in sorted order to minimize data movement.
What This Tests

Priority queues for tracking active range overlaps
Greedy boundary adjustment and state mutation
Sorting and deterministic processing order
