[FEATURE] Add the ATS resume checker in the Tools section

[ShroudAnkit53]

✨ Feature Description

Add an ATS Resume Score Checker tool that allows users to upload their resume and compare it against a job description. The tool will analyze keywords, formatting, and basic details (like contact info) to provide a score and suggestions for improvement.

---

🎯 Why is this Needed?

1. Helps job seekers optimize resumes for Applicant Tracking Systems (ATS), which are commonly used by recruiters.
2. Provides actionable feedback (missing keywords, formatting issues, length, contact info).
3. Complements existing document-related tools in the project by adding career-focused utility.

📋 Possible Implementation

Frontend

1. Build the tool using HTML, CSS, and JavaScript.
2. Use pdf.js (for PDF parsing) and mammoth.js (for DOCX parsing) to extract resume text directly in the browser.

Add input fields:

1. Resume upload (PDF/DOCX/TXT).
2. Job description text area.

Analyze and display:

1. ATS Score (0–100%)
2. Matched & missing keywords
3. Formatting checks (tables/images, length, contact info).
