refactor: update CoreMemory to v2 and rename OllamaToolResponse

- Refactored `CoreMemory` to support versioning (v2) and dual-memory types: `MAPPED_MEMORY` (key-value) and `ARRAYED_MEMORY` (sequential).
- Added automatic migration logic for v1 memory files to v2.
- Introduced new memory tools: `AddArrayMemory`, `GetArrayMemory`, and `GetArrayedMemories`.
- Renamed `OllamaToolRespnce` to `OllamaToolResponse` and added `empty()` factory methods for better error handling.
- Updated multiple function tools (e.g., `GetMemoryFunction`, `GetMemoriesFunction`, `APITool`, `GetWikiPageText`) to use the new `OllamaToolResponse` and `Optional`-based memory retrieval.
- Improved null safety by adding `@NotNull` annotations to tool implementations.
