Feature/config system expansion and docs cleanup

[YagoBorba]

📋 Description

This PR expands the StackCode configuration system and performs comprehensive documentation cleanup to ensure accuracy and reliability.

✨ New Features

• Expanded Configuration System: Added StackCodeConfig interface with defaultAuthor, defaultLicense, and features properties
• Configuration Utilities: Implemented loadStackCodeConfig() and saveStackCodeConfig() functions for managing project-specific settings
• Enhanced CLI Integration: Updated init and config commands to use the new configuration system

📝 Documentation Improvements

• Translation Status Fix: Removed incorrect "em desenvolvimento" and "en desarrollo" flags from README files - translations are actually complete
• SELF_HOSTING_GUIDE.md Cleanup: Thoroughly cleaned all 3 language versions (EN, PT-BR, ES) to remove non-implemented enterprise features
• Accuracy Verification: Ensured all documented features actually exist in the codebase

🗑️ Removed Documentation for Non-Implemented Features

• Private registry configuration sections
• Organization architecture and team integration features
• Advanced security configurations (VPN, audit logging, etc.)
• Enterprise deployment workflows
• Non-functional environment variables and configuration options
