A pure-Dart protocol synchronization library for Gantt Charts.

2.0.0

• FEAT: Improved Merkle Tree implementation with time-based bucketing (Hour/Day prefixes) and prefix-based traversal support.
• FEAT: Added computeMerkleTree to CRDTEngine for deterministic synchronization of tasks, resources, and dependencies.
• FEAT: Added lastUpdated (Hlc) to ProtocolResource.
• BREAKING CHANGE: Updated GanttSyncClient.syncWithMerkle signature to require a MerkleTree object.
• BREAKING CHANGE: Migrated ProtocolDependency.lastUpdated from int to Hlc for improved conflict resolution.
• FIX: Improved JSON deserialization for lastUpdated fields to support both String and Integer formats for backward compatibility.
