dx-forge 0.1.3

//! Comprehensive Test Suite for All Forge Features
//!
//! Tests:
//! 1. Content-Addressable Storage (SHA-256 blobs)
//! 2. CRDT Operations (conflict-free merging)
//! 3. Traffic Branch Detection (Red/Yellow/Green)
//! 4. LSP Detection (VS Code, language servers)
//! 5. R2 Cloud Storage (upload/download)
//! 6. Binary Blob Format (serialization)
//! 7. Parallel Operations (concurrent uploads)
//! 8. File Watcher (rapid & quality events)
//! 9. Web UI (file tree, syntax highlighting)
//! 10. Database Operations (SQLite oplog)
