chore: consolidate Syslog Solution code into unified repository structure

- Moved scattered scripts, templates, and documentation into organized directories (applications/, scripts/, assets/).
- Updated .gitignore to strictly exclude secrets, state files, and IDE configs.
- Added comprehensive README.md outlining repository structure and best practices.
- Preserved all existing documentation and technical architecture files.
- Prepared infrastructure/ for AWS Org and Proxmox Terraform management.

+# 01 - Proxmox & VM Passthrough — Home
+**Purpose:** Complete setup guide for Proxmox VM passthrough with optimal resource allocation.
+
+## Topics Covered
+
+- **GPU Passthrough:** Configure AMD/Intel/NVIDIA GPUs for VM access
+- **NVMe Passthrough:** Pass NVMe drives to VMs for high I/O performance
+- **USB Passthrough:** Connect USB devices (webcams, dongles, etc.) to VMs
+- **Networking:** Bridge networking, VLANs, and virtual switches
+- **Resource Allocation:** CPU cores, RAM, and storage optimization
+
+## Related Guides
+
+- **[00 - Proxmox & VM Passthrough](00 - Proxmox & VM Passthrough.md)** — This overview document
+- **[03 - AMD GPU Passthrough](../03\ -\ AMD\ GPU\ Passthrough/)** — AMD-specific setup
+
+## Quick Start
+
+### Create a VM with GPU Passthrough
+
+```bash
+# Step 1: Find available GPU
+rocm-smi | grep "GPU"  # AMD
+nvidia-smi             # NVIDIA
+
+# Step 2: Create VM with GPU passthrough
+qm create 100 --name qwen-vm --memory 32768 --cores 8 --arch x86_64
+qm set 100 --hostpci0=0000:03:00.0,pcie=1,x-vga=1  # AMD example
+
+# Step 3: Install QEMU Guest Agent
+apt install qemu-guest-agent
+
+# Step 4: Reboot VM
+qm reboot 100
+```
+
+## Best Practices
+
+1. **IOMMU Groups:** Always check if devices are in separate IOMMU groups
+2. **VFIO Modules:** Ensure `vfio-pci` module is loaded before boot
+3. **PCIe Hotplug:** Disable for stability unless required
+4. **Memory Ballooning:** Disable in VM for consistent performance
