Function write_optimized_stack 

pub fn write_optimized_stack(
    path: PathBuf,
) -> Result<MetricsBlockStore<DedupBlockStore<BloomBlockStore<CachedBlockStore<SledBlockStore>>>>>

Create a write-optimized production stack with deduplication

Optimized for write-heavy workloads with:

• Deduplication to reduce storage
• Smaller cache (100MB) to favor writes
• Bloom filter for existence checks
• Metrics tracking

Best for: Ingestion pipelines and write-heavy applications
