Description:
Request to add a Discord banner to the repository’s README.md to improve visibility of our community and provide a direct join link.

Proposed Solution:

Add Discord banner image (discord-banner.png) to assets/images/ directory.

Embed clickable banner in README.md linking to the official Discord invite.

Ensure banner placement aligns with existing header or community section formatting.

Rationale:
Improves onboarding and community engagement by making the Discord link visually accessible from the main repository page.
