[Copilot]

Resolved issues identified in code review of the testing and security framework implementation.

Test File Corrections

• Removed duplicate test suite (lines 34-66 in system-maintenance.Tests.ps1)
• Fixed Should -Not -Throw syntax to use proper script block wrapper

# Before
& $scriptPath -WhatIf | Should -Not -Throw

# After
{ & $scriptPath -WhatIf } | Should -Not -Throw

Pre-commit Configuration

• Removed unnecessary test file exclusion pattern from PSScriptAnalyzer hook
• Eliminated misleading "for now" comment suggesting temporary exclusion
