feat(§3.2): Replace Compress-Archive with 7-Zip (multi-threaded)

Browse Source 
§3.2 — Performance: Implement 7-Zip compression for artifacts with fallback
to Compress-Archive for compatibility. Three call sites updated:
1. Host-side source compression: new Compress-BuildArtifact helper function
2. Guest-side custom build artifacts: inline 7-Zip check in scriptblock
3. Guest-side dotnet build output: inline 7-Zip check in scriptblock

Uses 7z.exe with -mmt=on (multi-threaded) and -mx1 (fast, low ratio impact).
Falls back to Compress-Archive if 7-Zip not found (until §6.6 template update).

Expected 10-20s speedup per build once 7-Zip installed in template.

Also defer all security items (§1.2/1.3/1.5/1.7/1.8) to home-lab section
since environment is isolated and excessive for current use case.
