/**
 * Optional *structured* polish for known scanner outputs (nmap open ports,
 * ffuf hits, …). There is **no** generic keyword-ranker — arbitrary shell/fs
 * output is never "reduced" by guessing what looks interesting.
 *
 * Philosophy (clai):
 * - Eliminate noise at the **command** (flags, matchers, quiet modes).
 * - Long runs → durable background jobs with live artifact files; model uses
 *   shell.tail / head+tail / full file when needed.
 * - Model context gets honest head+tail + artifact path, not invented omissions.
