Build Fixes

v0.1.0.1 — PCAP Stream Namespace Build Fix

Fixed missing System.IO imports in:

• src/ARSVIN/Engine/AR.Iec61850/Capture/PcapReader.cs
• src/ARSVIN/Engine/AR.Iec61850/Capture/PcapWriter.cs

This resolves WPF temporary project build errors where Stream could not be resolved.

v0.1.0.2 — Single-project global usings build fix

Some embedded engine files reference File, Path, Directory, Stream, IOException, InvalidDataException, and FileNotFoundException. In the standalone ARSVIN single-project distribution these imports must be available consistently during WPF temporary project compilation.

Fixed by adding src/ARSVIN/GlobalUsings.cs with shared system imports for the embedded engine and app source.

v0.1.0.3 — WPF Vector ambiguity buildfix

Removed global using System.Numerics; from the single-project global imports. WPF controls use System.Windows.Vector, while numeric code keeps explicit using System.Numerics; where needed.
