monitor_core.ps1

#!/usr/bin/env pwsh
<#
InternetQualityMonitor Core Runner (Windows / PowerShell)
- Mirrors monitor_core.sh behavior
- Performs a measurement (collection) step, then an analysis step for the same SITUATION

Usage examples (PowerShell):
  # Defaults: Situation=Unknown, Parallel=1, Iterations=1, AnalysisBatches=15
  ./monitor_core.ps1

  # Override via parameters
  ./monitor_core.ps1 -Situation "Home_CorporateLaptop_CorpProxy_SequencedTest" -Parallel 2 -Iterations 1 -AnalysisBatches 15

  # Or via environment variables
  $env:SITUATION = "Home_CorpLaptop"; $env:PARALLEL = "2"; ./monitor_core.ps1

Prereqs:
- Go installed and on PATH
- PowerShell 7+ recommended (but script uses compatible constructs)
- Alternatively, you can run the .sh scripts using Git Bash or WSL
