tuxctl v0.2.0

v0.2 expands tuxctl's system monitoring capabilities while keeping the
application lightweight, responsive, and keyboard-first.

Highlights

• Redesigned Overview with dedicated System and Hardware dashboards
• Live aggregate and per-logical-CPU utilization
• Bounded CPU utilization history and load averages
• Live RAM usage and filesystem capacity
• GPU, storage, and physical network interface inventory
• Compact live network summary on Overview

• Improved Network counter lifecycle and recovery handling
• Correlated/coalesced Service refresh generations
• Bounded runtime histories, queues, and log storage

UI

• Removed redundant page titles across data screens
• Increased useful table/log viewport space
• Unified CPU/RAM gauge presentation
• Improved narrow-terminal tab layout
• Refined Overview CPU, RAM, storage, and Network presentation
