[plan] Documentation improvements from beginner user testing

[github-actions]

Overview

This tracking issue covers critical documentation improvements identified through fresh user perspective testing. The analysis revealed that while the documentation has excellent visual design, it assumes too much prior knowledge and lacks foundational explanations.

Source: Discussion #5738

Key Findings

Top 3 Blocking Issues:

1. No clear explanation of what "agentic" means
2. Compilation concept introduced too late
3. Prerequisites don't explain "why"

Planned Tasks

This work is broken into 5 focused tasks addressing the most critical issues:

1. Add conceptual foundation to home page - Define core concepts upfront
2. Improve Quick Start prerequisites explanation - Add context for each requirement
3. Fix Step 3 completion and PAT guidance - Complete instructions and add screenshots
4. Add early compilation explanation - Explain compilation before introducing commands
5. Create glossary and jargon definitions - Define technical terms throughout docs

Success Criteria

• New users can understand what agentic workflows are before installation
• Prerequisites section explains WHY each item is needed
• Quick Start guide is complete and includes visual guidance
• Compilation concept is clear from the beginning
• Technical jargon is defined inline or via tooltips

Notes

This addresses the "Quick Wins" category from the testing report - changes that help new users immediately with high impact and reasonable effort.

Medium and long-term improvements from the report can be addressed in future iterations based on user feedback.
