feat: add v5.8.0 features - transactions, pagination, and comprehensive docs
**Transaction System (TIER 1.2)** - Atomic operations with automatic rollback - 36 unit tests + 35 integration tests passing - Full documentation in docs/transactions.md **Duplicate Check Optimization (TIER 1.4)** - Optimized from O(n) to O(log n) using GraphAdjacencyIndex - Uses LSM-tree for efficient lookups - Tests verify performance improvements **GraphIndex Pagination (TIER 1.5)** - Production-scale pagination for high-degree nodes - Backward compatible API - 18 pagination tests passing **Comprehensive Filter Documentation (TIER 1.6)** - Complete operator reference (15 operators) - Compound filters (anyOf, allOf, nested logic) - Common query patterns and troubleshooting guide - 642 lines of new documentation **README Updates** - Added Filter & Query Syntax Guide to Essential Reading - Added Transactions to Core Concepts section All changes tested and production-ready for v5.8.0 release. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

/**

* Index Operations with Rollback Support
|

|

* Provides transactional operations for all indexes:

* - TypeAwareHNSWIndex (per-type vector indexes)

* - HNSWIndex (legacy/fallback vector index)
|

* - MetadataIndexManager (roaring bitmap filtering)
|
||||
* - GraphAdjacencyIndex (LSM-tree graph storage)
|
||||
*
|

* Each operation can be executed and rolled back atomically.
