function Invoke-TestsWithCoverage {
    <#
    .SYNOPSIS
        Runs unit tests with code coverage and returns coverage metrics.

    .PARAMETER TestProjectPath
        One or more paths to test project directories (or .csproj files). Each project
        is tested in order; coverage metrics are aggregated across all Cobertura outputs.

    .PARAMETER Silent
        Suppress console output (for JSON consumption).

    .PARAMETER ResultsDirectory
        Optional fixed directory where test result files are written.

    .PARAMETER KeepResults
        Keep the TestResults folder after execution.

    .OUTPUTS
        PSCustomObject with properties:
        - Success: bool
        - Error: string (if failed)
        - LineRate: double
        - BranchRate: double
        - MethodRate: double
        - TotalMethods: int
        - CoveredMethods: int
        - CoverageFile: string (ReportGenerator reports arg: one file, or semicolon-separated)
        - CoverageFiles: string[] (individual Cobertura paths)
        - ResultsDirectory: string (absolute folder used for dotnet test output; may be removed after run unless -KeepResults)

    .EXAMPLE
        $result = Invoke-TestsWithCoverage -TestProjectPath ".\Tests"
        if ($result.Success) { Write-TestRunnerLogInternal -Level "INFO" -Message "Line coverage: $($result.LineRate)%" }
