refactor: naturalize English copy with developer voice

Remove AI-generated phrasing patterns and replace with conversational
developer language. Key changes:
- Replace "always-learning mindset" with authentic expressions
- Use "I built for myself" storytelling approach for projects
- Simplify complex phrases like "bridge comprehension breaks"
- Make method card descriptions more conversational
