Use @z_ai/coding-helper wizard for easier GLM setup

MAJOR IMPROVEMENT to GLM setup workflow:

Before: Manual configuration with multiple steps
- Create settings.json manually
- Copy/paste complex JSON
- Edit files manually
- Easy to make mistakes

After: Interactive wizard ( MUCH simpler!)
- npm install -g @z_ai/coding-helper
- npx @z_ai/coding-helper init
- Wizard asks for API key
- Everything configured automatically
- Verified working

Benefits:
- ✅ Fewer steps (3 vs 6+)
- ✅ Less error-prone
- ✅ Interactive and guided
- ✅ Official Z.AI tool
- ✅ Automatic verification

Updates:
- MASTER-PROMPT.md: Promote wizard method as "EASIEST"
- README.md: Add wizard at top as primary method
- Blog post: Update warning with wizard commands
- Keep manual method as alternative

This makes GLM setup as simple as:
  npm install -g @z_ai/coding-helper
  npx @z_ai/coding-helper init
