Upgrade to SurrealDB 3.0 - Java SDK v3.0.0

[emmanuel-keller]

Overview

This PR upgrades the SurrealDB Java SDK to version 3.0.0, adding full compatibility with SurrealDB 3.0.

🎯 Major Changes

Version Upgrade

• Java SDK: 1.0.0-beta.1 → 3.0.0-SNAPSHOT
• SurrealDB Core: 2.3.1 → 3.0.0 (development branch)

Rust Layer Improvements

• Renamed Rust package from surrealdb to surrealdb-java for better clarity
• Refactored native JNI bindings to work with SurrealDB 3.0 APIs
• Updated all Rust dependencies to latest stable versions:
  • tokio 1.43.0 → 1.48.0
  • rust_decimal 1.36.0 → 1.39.0
  • chrono 0.4.39 → 0.4.42
  • parking_lot 0.12.3 → 0.12.5
  • once_cell 1.20.3 → 1.21.3

Feature Optimization

• Disabled default SurrealDB features and explicitly enabled only required features:
  • rustls for TLS support
  • protocol-http for HTTP connections
  • protocol-ws for WebSocket connections
• This results in smaller binary size and faster compilation

Code Quality

• Simplified and refactored Java and Rust source code
• Net reduction of ~290 lines of code across the codebase
• Improved test coverage and fixed test compatibility
• Enhanced code maintainability

🔧 Technical Details

Dependencies

The SDK now depends on SurrealDB 3.0 from the development branch:

surrealdb = { git = "https://github.com/surrealdb/surrealdb.git", 
              branch = "emmanuel/surrealdb.java", 
              default-features = false, 
              features = ["rustls", "protocol-http", "protocol-ws"] }
