feat(autoagents): enable experimental feature in cloud installation script

Update install-codegraph-cloud.sh to include autoagents-experimental:
- Add autoagents-experimental to FEATURE_FLAGS
- Update feature flag documentation comment
- Add AutoAgents to success message features list

Cloud installations will now include:
- AutoAgents ReAct framework integration
- All 7 agentic MCP tools using AutoAgents
- Tier-aware prompting with AutoAgents
- Experimental status clearly marked (🔬 EXPERIMENTAL)

Users can verify AutoAgents is active by checking server logs for
"🎯 AutoAgents" instead of "🎯 Agentic" when running agentic tools.

Completes AutoAgents integration for cloud deployment path.
