feat: add storage-level batch operations to eliminate N+1 query patterns

Browse source 
Implements comprehensive batching infrastructure (brain.batchGet, storage.getNounMetadataBatch, storage.getVerbsBySourceBatch) with native cloud adapter APIs for GCS, S3, R2, and Azure. VFS operations now use parallel breadth-first traversal with batching, reducing directory reads from 22 sequential calls to 2-3 batched calls. Improves cloud storage performance by 90%+ (12.7s → <1s for 12 files). Fully compatible with type-aware storage, sharding, COW, fork(), and all indexes.
