[BUG]: `typing.Self` ImportError on Python 3.10 — incompatible with Python < 3.11**

[luckyq]

Describe the Bug

Running python3 -m dynamo.frontend --help fails with an ImportError because dynamo/common/configuration/config_base.py imports Self directly from typing, which was only added in Python 3.11. Python 3.10 does not include typing.Self.

Steps to Reproduce

conda create -n myenv python=3.10
conda activate myenv
pip install -e .
python3 -m dynamo.frontend --help

Expected Behavior

Output the help info.

Actual Behavior

Environment

• OS: Rocky Linux 9.7.0 (x86_64)
• Python: 3.10.x (CPython, conda env)
• dynamo version: latest main

Additional Context

Root cause
typing.Self was introduced in Python 3.11 (PEP 673). The import in config_base.py should fall back to typing_extensions for Python < 3.11.

# components/src/dynamo/common/configuration/config_base.py
import sys
if sys.version_info >= (3, 11):
    from typing import Self
else:
    from typing_extensions import Self
