chore: bump version to 2.0.32 and port C++ engine logic

- Synchronized `GameLogic`, `GameType`, `DifficultyType`, `Grid`, `Room`, `Piece`, `PieceType`, `Block`, and `BlockType` classes in `src/main/java/com/bobsgame/puzzle` with the C++ codebase in `okgame`.
- Ported matching algorithms, parameters, game loops, garbage collection mechanisms, chain handlers, and serialization flags to strictly map to the C++ properties.
- Updated `VERSION.md`, `CHANGELOG.md`, and `HANDOFF.md` per universal project conventions.

+* **Version 2.0.32:** Comprehensive C++ (`okgame`) to Java puzzle logic parity port for core models. Added `okgame` submodule. Refactored `GameLogic`, `GameType`, `DifficultyType`, `Grid`, `Room`, `Piece`, `PieceType`, `Block`, and `BlockType` to fully align with C++ engine.

+### Additional Follow-Up - 2026-04-06 (Engine Logic Parity)
+- Cloned the `okgame` submodule for C++ reference.
+- Systematically aligned properties, configurations, fields, structs, array types, and serialization flags across Java's `Block`, `Piece`, `Grid`, `GameType`, `Room`, `GameSequence`, and `GameLogic`.
+- Implemented corresponding C++ logic algorithms like `flashChainBlocks`, `gotVSGarbageFromOtherPlayer`, `handleNewChain`, etc., matching the exact parity behavior intended.
+- Verified standalone Java file compilation via manual `javac` scripts because `./gradlew classes` encountered persistent HTTP 429 Rate Limits on repo.maven.org.
+- Bumped the Java repo version to `2.0.32`.
