.SYNOPSIS
    Plugin-driven test and coverage engine.

.DESCRIPTION
    Loads scriptsettings.json, builds shared execution context, and runs configured
    plugins in order. Each plugin implements Invoke-Plugin and receives its own
    settings plus shared context on Settings.context.

.USAGE
    pwsh -File .\Run-Tests.ps1
