Update WIKI.md with repository-specific URLs

[Copilot]

The WIKI.md documentation contained placeholder URLs that needed to be updated with the actual repository information.

Changes

• WIKI.md: Replaced generic placeholders with ewdlop/hello-algo:
  • Wiki URL example: username/repository-name → actual repository path
  • Image URL example: <user>/<repo> → actual repository path

Infrastructure Overview

All GitHub Wiki integration components were already implemented:

• Automated sync workflow (.github/workflows/sync-wiki.yml)
• Conversion script generating 107+ wiki pages (.github/scripts/sync-to-wiki.py)
• Comprehensive documentation (WIKI.md, 140 lines)

Activation Steps

1. Enable Wiki in repository settings
2. Create initial wiki page to initialize wiki repository
3. Workflow auto-syncs on docs/ changes or manual trigger
