docs: centralize all documentation via symlinks to /docs directory

CENTRALIZATION COMPLETED:
- Created symlinks from scattered docs folders to central /docs location
- All documentation now accessible from single entry point
- Maintained original file locations while providing centralized access

SYMLINKS CREATED:
✅ /docs/blockchain/node -> /apps/blockchain-node/docs
  - Content: SCHEMA.md (blockchain node schema)

✅ /docs/cli -> /cli/docs
  - Content: CLI documentation, cleanup analysis, organization summary

✅ /docs/contracts -> /contracts/docs
  - Content: ZK-VERIFICATION.md (zero-knowledge verification)

✅ /docs/testing -> /tests/docs
  - Content: Test documentation, refactoring status, usage guides

✅ /docs/website -> /website/docs
  - Content: HTML documentation for web interface

BENEFITS:
🎯 Single entry point for all documentation
🔄 Live updates through symlinks (no duplication)
📁 Clean organization while preserving context
🚀 Easy navigation and access

VERIFICATION:
✅ All symlinks tested and working
✅ Content accessible through central location
✅ Original locations preserved for editing
✅ No broken links or missing files

-## 🎯 Recent Changes (2026-03-26)
-
-### ✅ CLI Design Principles Applied
-- **Removed embedded servers** - CLI now controls services instead of hosting them
-- **Flattened directory structure** - Eliminated "box in a box" nesting
-- **Simplified HTTP clients** - Replaced async pools with basic calls
-- **Removed blocking loops** - Single status checks instead of infinite monitoring
-- **No auto-opening browsers** - Provides URLs for user control
-- **Removed system calls** - CLI provides instructions instead of executing
-
-### 📁 Documentation Consolidation
-- **Merged** `/cli/docs` into `/docs/cli` for single source of truth
-- **Organized** into implementation, analysis, guides, and legacy sections
-- **Updated** installation instructions for flat structure
-- **Purged** duplicate and outdated documentation
