Tsvika Shapira b1925368f9 refactor: migrate from os.path to pathlib.Path across codebase
Converted all path operations to use pathlib.Path instead of os.path module.
This modernizes the codebase and fixes all 135 ruff PTH violations.

Changes:
- Replace os.path.join() with Path / operator
- Replace os.path.exists() with Path.exists()
- Replace os.makedirs() with Path.mkdir()
- Replace open() with Path.open() where appropriate
- Replace os.remove() with Path.unlink()
- Replace os.getcwd() with Path.cwd()
- Replace os.path.expanduser("~") with Path.home()
- Add type hints for Path parameters in function signatures

All path objects are now created at first occurrence and propagated
through the codebase, eliminating unnecessary string conversions.
