Module compaction 

Sled compaction scheduling with lock-free atomics.

CompactionScheduler tracks write activity and decides when to trigger a Sled WAL flush / compaction. All state is held in atomics so the scheduler is cheaply shareable across threads without any mutex.

Decision logic

A compaction is recommended when any of the following hold and no compaction is already in progress:

• The store has been idle for at least CompactionConfig::idle_threshold and at least CompactionConfig::min_interval has elapsed since the last compaction.
• Bytes written since the last compaction exceed CompactionConfig::max_bytes_since_compact.
