v0.4.6 -- Error Handling, ServiceWhitelist, Test Coverage

Added

• ServiceWhitelist implementation -- config field now applied in service analysis to skip whitelisted services
• Test assertions -- Assert-FindingCount helper, double-extension detection, category coverage, severity/remediation/MITRE field validation, CIMode JSON suppressed key check

Fixed

• Error handling -- replaced silent empty catch {} blocks with Write-Verbose/Write-Status/Write-Warning in Check-Network.ps1, Helpers.ps1, and AmIHacked.ps1
• New-DefaultConfig $PSScriptRoot fix -- default path now resolves correctly to project root instead of lib/
