Issue #5: Quarantine System Implementation

Priority: High
Estimated Time: 3 days

Detailed Description:
Implement a secure quarantine system that can safely isolate malicious files while preserving their metadata for possible restoration.

Implementation Details:

1. Create src/quarantine/manager.rs:
2. Create src/quarantine/mod.rs:
3. Implement src/cli/quarantine.rs:
4. Update src/cli/mod.rs:
5. Update src/main.rs to add quarantine commands:

Acceptance Criteria:

• Quarantine system securely isolates malicious files
• Quarantined files have restrictive permissions to prevent execution
• Complete metadata is stored for each quarantined file
• Files can be quarantined by path with optional malware name
• Quarantined files can be listed, viewed individually, and restored
• Restoration requires confirmation to prevent accidental release of malware
• Quarantine database persists between program runs
• Implementation works correctly across all target platforms
• Error handling covers common edge cases (permission issues, missing files)
