[WIP] Update homepage to feature new newsletter edition

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Publish a new entry in the issues/ directory using the existing format and editorial style.

Update the homepage so the new edition appears as the most recent publication, while keeping previous editions accessible.

Ensure the tone remains professional, concise, and suitable for a technical newsletter.

Preserve the current design, structure, and deployment setup.

Commit the update with a clear editorial-style commit message.
