Net Speed Bar 1.2.0

[1.2.0] - 2026-04-10

Added

• Latency monitor: live ping measurement using TCP handshake RTT (Cloudflare, Google, or Apple DNS).
• Latency displayed in popover with color-coded status indicator (green/orange/red).
• Optional latency display in the menu bar.
• Settings for latency: enable/disable, ping target selection, show in menu bar.
• NetSpeedKit library: extracted testable core logic (traffic reader, speed formatter, latency monitor).
• 75 unit tests covering traffic snapshots, speed formatting, interface filtering, latency monitor lifecycle, and threshold alerts.

Changed

• Refactored Package.swift into three targets: MenuBarNetSpeed (app), NetSpeedKit (library), NetSpeedKitTests (tests).
• ViewModel delegates all formatting to SpeedFormatter for consistency and testability.
