chore(ci): update automated fidelity verification rules

[beginwebdev2002]

Updates the Automated Fidelity Verification script vibe-check-runner.js to adhere to the requested constraints:

1. Discovery: Now scans for both modified and new/untracked .md files using git ls-files -m -o --exclude-standard alongside the previous git log.
2. Execution: Temp generated AST analysis files now use temp_${tech}_${file}.ts to ensure concurrent generation doesn't overwrite.
3. Output: Update successful fidelity validation message to strictly commit with [chore: fidelity-pass].

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!
