fix python path problem mentioned in #14
restructures the entire codebase into a single, unified robonix Python package. All internal module imports now consistently use absolute paths starting with robonix. (e.g., from robonix.manager.node import *).
The start.sh script now automatically adds the project's root directory to the PYTHONPATH, ensuring the unified package is always discoverable at runtime.
