This commit adds FileChatMemoryRepository, a file-based implementation
of ChatMemoryRepository that stores chat messages as JSON files on the
local filesystem. Each conversation is stored in a separate file named
{conversationId}.json.
This implementation is useful for:
- Local development without database setup
- Testing with persistent memory across restarts
- Simple applications that need chat memory persistence
Features:
- Stores one JSON file per conversation
- Configurable storage directory (default: chat-memory)
- Uses Jackson for JSON serialization
- Thread-safe file operations
- Full support for UserMessage, AssistantMessage, SystemMessage types
