/**
 * WEVIA DEV PIPELINE v1.0 — Full Autonomous Development Cycle
 * 
 * PIPELINE (10 étapes):
 * 1. RECEIVE  → demande via chat/API
 * 2. ANALYZE  → parse intent, scope, impacted files
 * 3. SCAN     → wiki + L99 + architecture + 4 servers
 * 4. DEVELOP  → write code / fix bugs
 * 5. TEST     → L99 video long + Playwright + Selenium
 * 6. FIX      → corriger les bugs trouvés
 * 7. RETEST   → NonReg complet
 * 8. COMMIT   → git commit + checksums
 * 9. WIKI     → update wiki + L99 visual
 * 10. PUSH    → GitHub + Mattermost + Blade
