fix(scripts): add dot-source guard to Invoke-MsDateFreshnessCheck.ps1

[WilliamBerryiii]

Pull Request

Description

Add the standard if ($MyInvocation.InvocationName -ne '.') { ... } dot-source guard around the #region Main Logic block in Invoke-MsDateFreshnessCheck.ps1. This was the only script in the codebase missing the guard — all 18 other scripts already had it.

Without the guard, Pester's BeforeAll dot-source triggered the script's main logic (recursive file scan + exit call), hanging the test run indefinitely.

Closes #396

Type of Change

• 🐛 Bug fix (non-breaking change fixing an issue)

Component(s) Affected

• scripts/linting/ - Linting and validation scripts

Testing Performed

• All 1,038 Pester tests pass (deploy: 52, lib: 169, security: 232, linting: 585)
• The 37 tests in Invoke-MsDateFreshnessCheck.Tests.ps1 that previously hung now complete successfully
• No regressions across any test folder

Documentation Impact

• No documentation changes needed

Bug Fix Checklist

• Linked to issue being fixed
• Justification for no regression test: The 37 existing tests in Invoke-MsDateFreshnessCheck.Tests.ps1 serve as the regression tests — they now execute correctly instead of hanging
