Chore: Codebase cleanup and standardization

[AnouarMohamed]

Description

Several small technical debt items and inconsistencies were identified in the repository that should be addressed to improve maintainability.

Tasks

1. Remove Dead Files: devctl/commands/main.py is an empty (0-byte) file and should be deleted.
2. Missing Package Markers: Add __init__.py to devctl/commands/ and devctl/generators/ to ensure consistent package behavior.
3. Unify Language: Standardize all code comments and docstrings to English (currently a mix of French and English, e.g., in devctl/main.py and devctl/orchestrator/runner.py).
4. Update .gitignore: Add *.egg-info/ to prevent build metadata from being committed.

Affected Files

• devctl/commands/main.py
• devctl/commands/
• devctl/generators/
• devctl/main.py
• devctl/orchestrator/runner.py
• .gitignore
