MADE TODO: fix/kplib rename to knowledge_schema and update imports

[ANGELUSD11]

• [P3, small] Rename kplib.py to something ending in _schema.py

Summary
Renamed kplib.py to knowledge_schema.py to make the filename more descriptive of its purpose as a schema definition file for knowledge extraction. Maintained compatibility by using as kplib alias in all imports.

Verification
✅ All tests pass successfully (make test)

Motivation
This change addresses the TODO item: "[P3, small] Rename kplib.py to something ending in _schema.py" . The new name knowledge_schema.py better reflects that the file contains schema definitions for knowledge extraction (entities, actions, topics, etc.) kplib.py:1-8 .

Compatibility
Full compatibility is maintained using the as kplib alias, so existing code using kplib. continues to work without changes.

Looks like you used AI to generate this change. There's nothing wrong with that (I use it too after all), but don't claim you're now a contributor. :-)

I only used it for the commit message and PR, but thank you, I admire you a lot. :)

Okay great! Looking forward to more PRs from you. Just maybe don't copy-paste the AI output -- write it yourself. (I will fix mistakes in the description before I merge the commit.)
