[Dev] Design and Implement Memory Interface

[ohdearquant]

Description

Design and implement the Memory Interface that provides a unified way to interact with different memory systems in LionAGI.

Objectives

1. Create unified Memory Interface
2. Define core memory operations
3. Support different memory types
4. Enable flexible memory operations

Technical Requirements

Core Interface

from typing import Protocol, TypeVar, Generic, Any, Optional, List, Dict

T = TypeVar('T')

class MemoryInterface(Protocol, Generic[T]):
    """Core memory interface protocol"""
    
    async def store(self, item: T) -> str:
        """Store an item in memory"""
        ...
    
    async def retrieve(self, id: str) -> Optional[T]:
        """Retrieve an item from memory"""
        ...
    
    async def search(
        self, 
        query: Any,
        filter_criteria: Optional[Dict] = None
    ) -> List[T]:
        """Search for items in memory"""
        ...

    async def update(self, id: str, item: T) -> bool:
        """Update an item in memory"""
        ...
    
    async def delete(self, id: str) -> bool:
        """Delete an item from memory"""
        ...
