Agent Memory System

Multi-tier cognitive memory for AI agents, providing:
- Working Memory: Session-scoped ephemeral state (Redis/In-memory)
- Episodic Memory: Experiential records of past tasks (PostgreSQL)
- Semantic Memory: Learned facts and knowledge (PostgreSQL + pgvector)
- Procedural Memory: Learned skills and procedures (PostgreSQL)

Usage:
    from app.services.memory import (
        MemoryManager,
        MemorySettings,
        get_memory_settings,
        MemoryType,
        ScopeLevel,
    )

    # Create a manager for a session
    manager = MemoryManager.for_session(
        session_id="sess-123",
        project_id=uuid,
    )

    async with manager:
        # Working memory
        await manager.set_working("key", {"data": "value"})
        value = await manager.get_working("key")

        # Episodic memory
        episode = await manager.record_episode(episode_data)
        similar = await manager.search_episodes("query")

        # Semantic memory
        fact = await manager.store_fact(fact_data)
        facts = await manager.search_facts("query")

        # Procedural memory
        procedure = await manager.record_procedure(procedure_data)
        procedures = await manager.find_procedures("context")
