feat: auto-implement design changes via post-commit hook

- Add scripts/design-diff-analyzer.js to detect design changes
  • Analyzes ui-design.pen diff (colors, typography, spacing, layout)
  • Generates implementation tasks for Claude Code
  • Distinguishes content-only changes (no implementation)
- Add .git/hooks/post-commit to spawn Claude Code automatically
  • Triggers when ui-design.pen is committed
  • Spawns isolated sub-agent with auto-notify on completion
  • 10min timeout, auto-cleanup after done
- Update install-hooks.sh to install post-commit hook
- Document full workflow in .github/HOOKS.md

Workflow: commit design → analyzer runs → Claude Code spawns → implements → notifies Brian → Brian notifies Luca

Il repository ha un pre-commit hook che verifica la qualità del codice prima di ogni commit.
## Post-Commit Hook: Auto-Implement Design Changes
Quando committi modifiche a `ui-design.pen`, il post-commit hook:
1. Analizza automaticamente le modifiche (colori, typography, spacing, layout)
2. Spawna Claude Code in background per implementare le modifiche
3. Ti notifica quando l'implementazione è completa

## Post-Commit Hook: Auto-Implement Design Changes
### Cosa Fa
Quando committi modifiche a `ui-design.pen`, il hook:
1. **Analizza il diff** — usa `scripts/design-diff-analyzer.js`
2. **Identifica modifiche significative:**
- 🎨 Colori (fill, backgroundColor)
- 📝 Typography (fontSize, fontFamily)
- 📏 Spacing (padding, margin, gap)
- 🔲 Layout (nuovi componenti, riorganizzazioni)
3. **Spawna Claude Code** — in background via `openclaw sessions spawn`
4. **Auto-notifica** — quando l'implementazione è completa
### Cosa Implementa
| Tipo Modifica | Azione |
|--------------|--------|
| Colori | Aggiorna `src/theme.json` o CSS variables |
| Typography | Aggiorna `src/theme.json` typography |
| Spacing | Aggiorna `src/theme.json` spacing |
| Layout | Modifica/crea componenti React |
| Testi mockup | Nessuna azione (solo design) |
### Esempio Output
```
🎨 Design file changed - analyzing...
📋 Implementation tasks:
1. [HIGH] Update color palette
- fill: $--muted-foreground → #666666
- backgroundColor: #FFFFFF → #F5F5F5
Update src/theme.json or CSS variables to match the design.
2. [MEDIUM] Update typography
- fontSize: 14px → 16px
Update src/theme.json typography settings.
🚀 Spawning Claude Code to implement changes...
✅ Claude Code spawned - you'll be notified when implementation is complete

```
### Design Diff Analyzer
Lo script `scripts/design-diff-analyzer.js` rileva:
- **Color changes** — `"fill": "#OLD" → "#NEW"`
- **Font changes** — `"fontSize": 14 → 16`
- **Spacing** — `"padding": 8 → 12`
- **Content** — testi mockup (no implementation)
Uso:
```bash
# Analizza ultimo commit
node scripts/design-diff-analyzer.js
# Output JSON per automation
node scripts/design-diff-analyzer.js --json
```
### Disabilitare Temporaneamente
Se vuoi committare il design senza auto-implementazione:
```bash
# Disabilita hook
mv .git/hooks/post-commit .git/hooks/post-commit.disabled
# Commit
git commit -m "design: update mockup"
# Riabilita hook
mv .git/hooks/post-commit.disabled .git/hooks/post-commit
```
### Monitorare Claude Code
Mentre Claude Code lavora in background:
```bash
# Lista sub-agent attivi
openclaw sessions list --kinds isolated
# Vedi log di un sub-agent
openclaw sessions history --session-key <key>
# Ferma sub-agent (se necessario)
openclaw subagents kill --target design-auto-implement
```
### Troubleshooting
**Hook non parte:**
- Verifica che `ui-design.pen` sia effettivamente cambiato: `git diff HEAD~1 ui-design.pen`
- Verifica che lo script analyzer esista: `ls -la scripts/design-diff-analyzer.js`
**Nessuna notifica:**
- Claude Code potrebbe essere ancora in esecuzione — controlla `openclaw sessions list`
- Verifica che il prompt includa `openclaw system event` al termine
**Modifiche non implementate:**
- Controlla i log di Claude Code: `openclaw sessions history --session-key <key>`
- Il sub-agent viene auto-eliminato dopo completion (cleanup=delete)
### Limitazioni
- **Modifiche complesse** — layout completamente nuovi potrebbero richiedere intervento manuale
- **Timeout** — 10 minuti max (configurabile in hook)
- **Solo modifiche recenti** — analizza solo HEAD vs HEAD~1

Design changes detected:

Tasks:
1. Review the git diff of ui-design.pen (HEAD vs HEAD~1)
2. Identify what changed (colors, typography, spacing, layout)
3. Update the corresponding code:
- Colors/Typography/Spacing → update src/theme.json
- Layout changes → update React components
- New elements → create new components
4. Test visually in Chrome (pnpm dev, open localhost:5173)
5. Run tests: pnpm test
6. Commit changes with descriptive message referencing the design update
When completely finished, run:
openclaw system event --text "✅ Design changes implemented and tested" --mode now
