fix: resolve circular import by renaming aitbc.logging module

CIRCULAR IMPORT FIX: Avoid conflict with Python built-in logging

Issue:
- aitbc/logging.py conflicts with Python's built-in logging module
- Circular import when pip tries to import logging
- AttributeError: partially initialized module 'logging' has no attribute 'Logger'

Solution:
- Rename aitbc/logging.py to aitbc/aitbc_logging.py
- Update aitbc/__init__.py to import from renamed module
- Maintains same API (get_logger, setup_logger)
- Avoids naming conflict with built-in logging

Expected results:
- No more circular import errors
- pip should work properly
- aitbc.logging imports should still work
- Test workflow should proceed to execution

This resolves the circular import that was blocking pip
and preventing the test workflow from running.
