refactor: remove dead variables $config in Test-FeatureFlag begin{} and $validation in Test-Condition

[HeyItsGilbert]

Summary

Two variables are assigned but never used. PSScriptAnalyzer flags both with PSUseDeclaredVarsMoreThanAssignments.

Files

File	Line	Variable	Source	Issue
Public/Test-FeatureFlag.ps1	41	$config	Import-GatekeeperConfig	Config reloaded by Invoke-Logging internally; this call is dead
Public/Test-Condition.ps1	86	$validation	$meta.Validation	Validation is passed via $meta to Test-TypedValue; $validation is never referenced

Fix

Remove both assignments:

# Test-FeatureFlag.ps1 begin{} — remove this line:
$config = Import-GatekeeperConfig

# Test-Condition.ps1 — remove this line:
$validation = $meta.Validation
