feat: add permission interpreter, junks, ports, usages, network commands

New Commands:
- z network: Show IP addresses, public IP, DNS servers, active connections
- z ports: List listening ports with process/PID info
- z usages: All processes sorted by resource usage with filtering
- z junks: Find and clean junk files (caches, temporary files)

Enhancements:
- Permission interpreter in z info file - shows human-readable permissions
  e.g. -rw-rw-r-- → "Owner can read, write; Group can read, write; Other can read"
- z usages now supports filtering: z usages chrome -m -n=50
- Summary section shows total CPU/memory when filtering by name
- Added help entries for all new commands
