Add Incremental Output Mode for Large-Scale Network Reconnaissance

Describe the current behavior
A clear and concise description of what the bug or current behavior is.
Describe the current behavior

When scanning large network segments with Nmap, users must wait until the scan completes before viewing results. This creates a poor user experience for long-running assessments as operators lack real-time visibility into discovered services.

Expected behavior

Add an --incremental-output flag that streams discovered hosts and services as they're found, similar to how Nmap currently displays output in interactive mode but written to a parseable format.

Motivation

This would allow penetration testers to:

• React immediately to discovered critical services
• Identify and focus on high-value targets during active scans
• Export partial results without waiting for full completion
• Integrate with automated workflow systems more effectively

Describe what you would like to happen instead.

The issue names no files, tests, or entry points. Start by locating Nmap's existing interactive and parseable output paths, then define how an --incremental-output mode should stream discovered hosts and services while remaining parseable; done means partial results are available before the scan completes.
