Add comprehensive cross-project compatibility report

[AdaWorldAPI]

Summary

This PR adds a detailed compatibility analysis document (COMPATIBILITY_REPORT.md) that evaluates neo4j-rs against related projects in the Ada ecosystem: ladybug-rs, n8n-rs, crewAI/crewai-rust, and aiwar-neo4j-harvest.

Key Changes

• New document: docs/COMPATIBILITY_REPORT.md (397 lines)
  • Dependency alignment matrix across 5 projects with version compatibility analysis
  • Detailed integration assessment for neo4j-rs ↔ ladybug-rs (designed to integrate via StorageBackend trait)
  • Integration architecture diagrams showing how neo4j-rs fits into n8n-rs workflows
  • Bridge analysis for crewAI (Python) and crewai-rust (Rust port) integration paths
  • Migration strategy for aiwar-neo4j-harvest from neo4rs 0.8 to neo4j-rs
  • Risk assessment and phased integration roadmap

Notable Details

• No version conflicts identified: All projects share compatible Tokio (1.35-1.49), serde, and async-trait versions
• StorageBackend trait as integration linchpin: Documents how the existing trait contract enables ladybug-rs, n8n-rs, and crewAI to leverage neo4j-rs capabilities
• Concrete mapping tables: Shows how neo4j-rs concepts (NodeId, labels, relationships) map to ladybug-rs (BindSpace addresses, fingerprints, 144 cognitive verbs)
• 7 AI War patterns analysis: Demonstrates how the harvested graph patterns naturally fit the full stack
• Phased roadmap: Prioritizes LadybugBackend implementation as Phase 1 foundation for downstream integrations

This document serves as a reference for architecture decisions and integration planning across the Ada ecosystem.
