v0.0.3

What's New

Display Modes

• Three view modes — cycle with V between Default, Extended, and Compact layouts
• Each mode shows a different set of columns tuned for the terminal width

Sparklines

• Per-hop latency sparklines rendered with heat-colored block characters
• Color ramps from green (low) through yellow to red (high latency)
• Sparklines fed from ping supplement data for rate-limited hops

Alert Engine

• Real-time threshold alerting for latency spikes and packet loss
• State machine tracks per-hop alert state (OK → Warning → Alert → Cleared)
• Configurable via --alert-latency and --alert-loss CLI flags

New Metrics

• Geometric Mean — robust central tendency less sensitive to outliers
• Jitter / Jitter Mean — inter-probe latency variation
• Hop Delta — latency difference from the previous hop
• Trend — sliding-window linear regression showing latency direction (↑↓→)

Responsive Layout

• Budget-based column fitting — gracefully scales columns from 40ch terminals to 160ch+ ultrawide
• Progressive disclosure: narrow terminals show core metrics, wider terminals add sparklines, ASN, jitter, trend

Windows Installer

• Native Windows installer (.exe) for both amd64 and arm64
• Adds via to PATH automatically on install
• Clean uninstall via Windows Add/Remove Programs
