lmiranda 747a2b15e5 refactor(cmdb-assistant): extract skills and slim commands

- Extract 9 skill files from command knowledge:
  - mcp-tools-reference.md: Complete NetBox MCP tools reference
  - system-discovery.md: Bash commands for system info gathering
  - device-registration.md: Device registration workflow
  - sync-workflow.md: Machine sync process
  - audit-workflow.md: Data quality audit checks
  - ip-management.md: IP/prefix management and conflict detection
  - topology-generation.md: Mermaid diagram generation
  - change-audit.md: NetBox change audit workflow
  - visual-header.md: Standard visual header pattern

- Slim all 11 commands to under 60 lines:
  - cmdb-sync.md: 348 -> 57 lines
  - cmdb-register.md: 334 -> 51 lines
  - ip-conflicts.md: 238 -> 58 lines
  - cmdb-audit.md: 207 -> 58 lines
  - cmdb-topology.md: 194 -> 54 lines
  - initial-setup.md: 176 -> 74 lines
  - change-audit.md: 175 -> 57 lines
  - cmdb-site.md: 68 -> 50 lines
  - cmdb-ip.md: 65 -> 52 lines
  - cmdb-device.md: 64 -> 55 lines
  - cmdb-search.md: 46 lines (unchanged)

- Update agent to reference skills for best practices
- Preserve existing netbox-patterns skill

System Discovery Skill

Bash commands for gathering system information from the current machine.

Basic Device Information

# Hostname
hostname

# OS/Platform info
cat /etc/os-release 2>/dev/null || uname -a

# Hardware model - Raspberry Pi
cat /proc/device-tree/model 2>/dev/null || echo "Unknown"

# Hardware model - x86 systems
cat /sys/class/dmi/id/product_name 2>/dev/null || echo "Unknown"

# Serial number - Raspberry Pi
cat /proc/device-tree/serial-number 2>/dev/null || cat /proc/cpuinfo | grep Serial | cut -d: -f2 | tr -d ' ' 2>/dev/null

# Serial number - x86 systems
cat /sys/class/dmi/id/product_serial 2>/dev/null || echo "Unknown"

# CPU count
nproc

# Memory in MB
free -m | awk '/Mem:/ {print $2}'

# Disk size in GB (root filesystem)
df -BG / | awk 'NR==2 {print $2}' | tr -d 'G'

Network Interfaces

# Get interfaces with IPs (JSON format)
ip -j addr show 2>/dev/null || ip addr show

# Get default gateway interface
ip route | grep default | awk '{print $5}' | head -1

# Get MAC addresses
ip -j link show 2>/dev/null || ip link show

Running Applications

# Docker containers (JSON format)
docker ps --format '{"name":"{{.Names}}","image":"{{.Image}}","status":"{{.Status}}","ports":"{{.Ports}}"}' 2>/dev/null || echo "Docker not available"

# Docker Compose projects (find compose files)
find ~/apps /home/*/apps -name "docker-compose.yml" -o -name "docker-compose.yaml" 2>/dev/null | head -20

# Running systemd services
systemctl list-units --type=service --state=running --no-pager --plain 2>/dev/null | grep -v "^UNIT" | head -30

Interface Type Mapping

Interface Pattern	NetBox Type
`eth`, `enp`	`1000base-t`
`wlan*`	`ieee802.11ax`
`tailscale`, `docker`, `br-*`	`virtual`
`lo`	Skip (loopback)

Platform Detection

Based on OS detected, determine platform name:

OS Detection	Platform Name
Raspberry Pi OS	`Raspberry Pi OS (Bookworm)`
Ubuntu	`Ubuntu {version} LTS`
Debian	`Debian {version}`
Default	`{OS Name} {Version}`

Device Role Auto-Detection

Based on detected services:

Detection	Suggested Role
Docker containers found	`Docker Host`
Only basic services	`Server`
Specific role specified	Use specified

Container Role Mapping

Map container names/images to roles:

Container Pattern	Role
`caddy`, `nginx`, `traefik`	Reverse Proxy
`db`, `postgres`, `mysql`, `redis`	Database
`webui`, `frontend`	Web Application
Others	Infer from image or use "Container"
