📄 Description

Problem

DecisionLog and FailureBanner are defined in mlsysim/labs/components.py and imported directly by 14+ lab notebooks, but were missing from mlsysim/labs/__init__.py.

Any lab using the public API:

from mlsysim.labs import DecisionLog
from mlsysim.labs import FailureBanner

raises ImportError at runtime.

Fix

Add both to the import block and __all__ in mlsysim/labs/__init__.py.

Verification

from mlsysim.labs import DecisionLog, FailureBanner  # ✓
