Add English translation of agentic 101 presentation with AI transparency

[Copilot]

This PR addresses the issue that the "agentic 101" README.md was only available in German by providing a complete English translation with full transparency about AI assistance used.

Changes

Added README_EN.md - a comprehensive English translation of the German presentation about "Vibe Coding" and AI-assisted development, with clear documentation of AI assistance used in the translation process.

What's Included

The English translation covers the complete presentation content:

• Introduction and Background: Personal introduction, experience, and context
• Core Concepts: Definitions of "Vibe Coding" vs "Agentic Coding" and their applications
• Tools Overview: Analysis of AI development tools (Cursor, Windsurf, GitHub Copilot, Cline, etc.)
• Use Cases: Practical applications from code completion to security reviews
• Case Studies: Detailed Chrome plugin development example using GitHub Copilot
• Technical Deep Dive: LLM fundamentals, components, and architecture patterns
• Real Experiences: Personal insights on hallucinations, skepticism, and practical value
• Q&A Section: Discussion points and overflow topics

Translation Quality & Transparency

• AI Transparency: Added clear translation note specifying Claude 3.5 Sonnet (Anthropic) was used via GitHub Copilot for the English translation
• All external links, GitHub references, and image paths preserved exactly
• Technical terminology maintained appropriately (LLM, AI, etc.)
• Presentation slide format and structure kept intact
• German-specific context handled appropriately while maintaining accessibility
• Code blocks and examples preserved without modification

The English version makes this valuable technical content about AI-assisted development accessible to international audiences while maintaining the original's technical depth and practical insights, with full transparency about the AI assistance used in the translation process.
