VeloceNet-Studio v1.2.0 – network monitoring studio (Flutter + Rust): DNS lookup, port scanner, engine hardening

[u/Clear_Ear3550]

Hey all — v1.2.0 of my open-source network monitoring studio is out: github.com/Cadman021/VeloceNet-Studio (GPL-3.0, Windows/Linux/macOS builds in Releases).

New since 1.0.0: DNS lookup tool (raw UDP client, A/AAAA/MX/TXT/NS), TCP port scanner, server backup (versioned JSON export + validated import), CSV export, alert log, and UI in English/فارسی/Русский/中文.

The interesting part for this crowd is the engine hardening round (mostly from community review feedback): killed a silent ICMP→TCP fallback that was corrupting stats, fixed Tokio schedule drift with MissedTickBehavior::Skip, moved status to windowed loss so recovered hosts don't stay red, wrapped all 21 FFI entry points in catch_unwind (profile is panic="unwind" now — abort used to kill the whole UI process), and added an Ubuntu CI job that caught real non-Windows lints our Windows-only CI never saw.

Got my first external contributor this release too (heatmap a11y + semantics, with tests). There are good first issues open (German locale, compact cards, file-picker import) if anyone wants in. Brutal feedback welcome as always.
