docs: add [OutputType()] declarations and .OUTPUTS help to Test-FeatureFlag and Test-Condition

[HeyItsGilbert]

Summary

Both Test-FeatureFlag and Test-Condition always return [bool] but neither declares an [OutputType()] attribute nor a .OUTPUTS help block. For functions whose entire purpose is to return a boolean that gates behavior, this is a missing piece of the public contract.

Files

• Gatekeeper/Public/Test-FeatureFlag.ps1
• Gatekeeper/Public/Test-Condition.ps1

Fix

Add to each function:

function Test-FeatureFlag {
    [CmdletBinding()]
    [OutputType([bool])]
    param (
        ...
    )

    <#
    .OUTPUTS
    System.Boolean
    Returns $true if an Allow rule matches, $false otherwise.
    #>

Then regenerate the external help XML with PlatyPS so the ## OUTPUTS section in the .md files is populated.
