fix: remove .html extensions from all internal links for Jekyll pretty URLs

- Fixed 404 links across 53 markdown files
- Converted [text](file.html) to [text](file) format
- Created Fix-HtmlLinks.ps1 script with backup capability
- All backups created with timestamps

This resolves broken navigation throughout the site as Jekyll uses pretty URLs
without .html extensions (e.g., /level-100/azure-local-overview/ not .html)

+
+1. **Connected Operations**
+   - Seamless Azure integration
+   - Cloud-managed control plane via Azure Arc
+   - Hybrid Azure services (Monitor, Backup, Defender)
+   - Continuous updates from Azure
+
+2. **Disconnected Operations**
+   - Air-gapped environments
+   - Local control plane
+   - Highest operational sovereignty
+   - Manual update delivery
+
+**Common Use Cases:**
+- Branch office infrastructure
+- Data center modernization
+- Latency-sensitive workloads
+- Data residency requirements
+- Virtual Desktop Infrastructure (VDI)
+- Kubernetes at the edge
+
+### Azure Arc
+

+- Unified governance and compliance
+
+### Retrieval-Augmented Generation (RAG) on Azure Arc for Edge
+
+**[Learn More →](https://learn.microsoft.com/en-us/azure/azure-arc/edge-rag/)**
+
+Edge RAG enables generative AI solutions on on-premises data without moving data to the cloud.
+
+**Key Features:**
+- Search on-premises data with generative AI
+- Data privacy and sovereignty
+- Low-latency AI inference
+- Custom model support (BYOM)
+- Integration with Azure AI services
+
+**Architecture Components:**
+- AKS Arc cluster for compute
+- NFS server for data storage
+- Language models (Microsoft-provided or custom)
