Phase 2.5: when DLP policy rule has action="block", the collector
now actively prevents the action instead of just logging:
- USB: Set-Disk -IsReadOnly via Get-Partition/Get-Disk pipeline
- Print: Remove-CimInstance Win32_PrintJob for matching jobs
- Clipboard: Set-Clipboard -Value $null to clear sensitive content
Each enforcement adds enforced=true/false to incident telemetry.
Windows balloon notification shown to user on every block action.
Backward-compatible: existing action="alert" rules unchanged.
