LinkedIn selectors break when LinkedIn updates DOM

[Aftab553911]

Problem

LinkedIn frequently updates their CSS class names and DOM structure.
When this happens, content.js selectors stop working and the extension
shows "Click on a job posting first" even when a job is open.

Current selectors location

JobTruth.Extension/content.js and JobTruth.Extension/popup.js
inside the extractFromPage() function.

What needs to be done

• Test the extension on a fresh LinkedIn job page
• Identify which selectors are failing
• Add updated selectors as fallbacks
• Test on both:
  • Direct job URL: linkedin.com/jobs/view/xxxxx
  • Search results panel: linkedin.com/jobs/search/

How to test

1. Open Chrome with the extension loaded
2. Go to linkedin.com/jobs
3. Search for any job
4. Click a result
5. Click the JobTruth icon
6. Check browser console for [JobTruth] Extracted: logs

Acceptance criteria

• Job title is extracted correctly
• Company name is extracted correctly
• Company LinkedIn URL is extracted correctly
• Works on direct job page
• Works on search results panel
