fix: add repo root to sys.path in cli.py and server.py to resolve ModuleNotFoundError

[s0wa48]

Summary

• Running python scripts/python/cli.py from the repo root failed with ModuleNotFoundError: No module named 'agents' because the repo root was not in Python's module search path.
• The README mentioned setting export PYTHONPATH="." as a workaround, but this required manual setup and didn't work on Windows with the export syntax.
• This fix adds sys.path.insert(0, ...) at the top of cli.py and server.py to programmatically add the repository root to sys.path, so the agents package is always findable regardless of how or where the scripts are invoked.

Fixes #28

Note

Low Risk
Low risk: only adjusts Python module search path for scripts/python/cli.py, with no changes to business logic; main risk is unintended import shadowing if similarly named modules exist on the path.

Overview
Fixes ModuleNotFoundError when running scripts/python/cli.py directly by prepending the repository root to sys.path via sys.path.insert(0, ...) before importing agents modules.

Both 'original' texts exist verbatim in their respective files, and the edits correctly address the issue by wrapping the path with os.path.abspath() and also applying os.path.abspath() to file before dirname(), ensuring an absolute path is always inserted into sys.path regardless of how the script is invoked.
