"""
VPC CLI - Click-based command-line interface with Universal Output Format Support

Manager-friendly VPC cost analysis and decommissioning tools with Rich CLI patterns
from FinOps, Inventory, Operate, and Security modules.

Features:
- Network topology tree displays
- Dependency graph tables (VPC → Subnets → ENIs → Resources)
- Cost impact visualization (NAT Gateway costs, data transfer)
- Connectivity maps (routing, peering, transit gateway)
- Universal output format support (CSV, JSON, Markdown, Table)
