bug: get_allow_recursion() comment contradicts return value

[RyanLHicks]

In config.py, get_allow_recursion() has a comment that contradicts its behavior:

if val is None:
    return True  # Default to False for safety

The comment says "Default to False for safety" but the function returns True when no config value is set.

Two possible fixes depending on intent:

• If True is correct: update the comment to match
• If False was intended: update the return value to match

Flagging for clarification before touching either.
