Subject: [PATCH] Add missing stacklevel=2 to 9 warnings.warn() calls

Without stacklevel, warnings.warn() reports the location of the warn()
call itself rather than the caller's location, making it harder for
users to identify the source of the warning in their own code.

This adds stacklevel=2 to all 9 warnings.warn() calls across 7 files
that were missing it.
