Clean up codebase: Remove obsolete files, add PEP-257 docstrings, eliminate non-English comments

[Copilot]

Addresses technical debt by removing obsolete documentation, eliminating non-English comments, and adding comprehensive PEP-257 docstrings to core modules for production readiness.

Changes

Removed obsolete files (8 total)

• Duplicate implementation summaries: IMPLEMENTATION_SUMMARY.md, IMPLEMENTATION_SUMMARY_NEW.md, tests/dummy_servers/IMPLEMENTATION_SUMMARY.md
• Implementation detail doc: CURSOR_AND_COLORS_DOCUMENTATION.md
• Demo scripts masquerading as tests: demo_fps_speed_timing.py, demo_resnet_spectrogram_integration.py, demo_spectrogram_colormap.py, demo_spectrogram_scrolling.py

Internationalized codebase

• Translated French comments to English in basenode.py and sound.py
• No Japanese characters found in codebase

Added PEP-257 docstrings to core modules

• main.py: Module, all functions with parameter/return documentation
• node_abc.py: Abstract base class with complete interface documentation
• basenode.py: Module, DataType/PortType/Node classes, all methods
• _node_image.py: Module, FactoryNode/ImageNode classes, all methods
• __init__.py, sound.py: Module docstrings

Code cleanup

• Removed unused variables in main.py (editor_width, editor_height)

Example

Before:

class Node:
    def __init__(self, node_id=1, connection_dict=None, opencv_setting_dict=None):
        # Paramètres OpenCV
        self._opencv_setting_dict = opencv_setting_dict if opencv_setting_dict else {}

After:

class Node:
    """Base class for all nodes in the CV Studio node editor.
    
    Provides common functionality for all node types including image conversion,
    input/output handling, and configuration management.
    """
    
    def __init__(self, node_id=1, connection_dict=None, opencv_setting_dict=None):
        """Initialize a new Node instance.
        
        Parameters
        ----------
        node_id : int, optional
            Unique identifier for this node instance. Default is 1.
        connection_dict : dict, optional
            Dictionary defining the node's connections. Default is None.
        opencv_setting_dict : dict, optional
            Configuration dictionary for OpenCV and application settings.
        """
        # OpenCV parameters
        self._opencv_setting_dict = opencv_setting_dict if opencv_setting_dict else {}

Original prompt

retire les .md obsoletes inutiles, les tests inutiles, le code inutile si il y en a , le code en japonais, et documente les signatures comme il se doit en pep, avec doc string d'explication de code et signatures de methode. simplifie si possible, en faisant du code un code production ready
