feat: scaffold MemoryService for Agent Episodic Memory (URT migration)

Add MemoryService client backed by ECS (/ecs_/memory/...) endpoints for
Agent Episodic Memory. This enables dynamic few-shot retrieval where
agents query past episodes at execution start and inject them as
examples into the system prompt.

New files:
- memory.py: Pydantic models (MemoryField, MemoryItem, MemoryQueryRequest, etc.)
- _memory_service.py: MemoryService with create, ingest, query, retrieve, delete, list
- __init__.py: Module exports

Also registers sdk.memory on the UiPath class.
