/**
 * urlVerifier.ts — URL safety & reachability checker for the CareerVivid Job Agent.
 *
 * Harness Engineering Mindset:
 *   The agent must think like a real user clicking a link. A 98%-match job means
 *   nothing if the URL is broken, hallucinated, or redirects to a homepage.
 *   Every URL we return to the user must pass this verification harness BEFORE
 *   we present it.
 *
 * The harness performs layered checks:
 *   1. Structural validity — is this even a parseable URL?
 *   2. Domain plausibility — does this look like a real company domain?
 *   3. HTTP reachability — does it respond with 200/301/302?
 *   4. Content sanity   — does the final page look like a real job listing?
 *   5. ATS legitimacy   — is it on a known ATS (Ashby, Greenhouse, Lever, etc.)?
