feat: add distributed architecture with sharding and coordination
- Wire up distributed components (Coordinator, ShardManager, CacheSync) - Implement automatic sharding for S3 storage (256 shards) - Add read/write separation for operational modes - Zero-config automatic detection for distributed mode - Add mutex implementation for thread safety - Fix metadata filtering in find operations - Fix neural API vector similarity calculations - Improve batch operations performance - Add Bluesky distributed setup example BREAKING CHANGE: None - backward compatible

* DEPLOYMENT NOTES:

*
|

* 1. DOCKER DEPLOYMENT:
|
||||
* docker run -e MODE=writer -e NODE_ID=writer-0 brainy-writer
|
||||
* docker run -e MODE=reader -e NODE_ID=reader-0 brainy-reader
|
||||
*
|
||||
* 2. KUBERNETES DEPLOYMENT:
|
||||
* kubectl apply -f brainy-writers-deployment.yaml # 4 replicas
|
||||
* kubectl apply -f brainy-readers-deployment.yaml # 8 replicas
|
||||
*
|
||||
* 3. LOAD BALANCING:
|
||||
* - Put readers behind an ALB/NLB
|
||||
* - Writers don't need load balancing (each handles specific shards)
|
||||
*
|
||||
* 4. MONITORING:
|
||||
* - Use Prometheus/Grafana for metrics
|
||||
* - CloudWatch for S3 access patterns
|
||||
* - Datadog for distributed tracing
|
||||
*
|
||||
* 5. SCALING:
|
||||
* - Writers: Add more nodes and redistribute shards
|
||||
* - Readers: Simply add more nodes behind load balancer
