update CLAUDE.md: include decision graph in code commits

Added guidance to run deciduous sync before commits and stage graph
updates together with code changes. Decision graph is part of code
history and should not be committed separately.

 ### Git History & Deployment
 
+**CRITICAL: Include decision graph in code commits**
+
+Always run `deciduous sync` BEFORE committing code changes, then include the graph updates in the same commit:
+
+```bash
+# After making code changes and adding decision nodes:
+deciduous sync                    # Export graph
+git add src/your-file.ts docs/    # Stage code + graph
+git commit -m "your change"       # Single commit with both
+```
+
+**DO NOT create separate commits for graph updates.** The decision graph is part of the code history and should be committed together.
+
 ```bash
 # Export graph AND git history for web viewer
 deciduous sync
