Hello @tac0turtle, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly streamlines the repository by eliminating the x402 demo and all its related files. This cleanup effort removes a substantial amount of code and documentation, reducing the overall complexity and footprint of the codebase. The change also includes a minor update to a doc comment to ensure it remains relevant and generic after the demo's removal.

• Doc Comment Generalization: A doc comment in bin/evd/src/main.rs was updated to use a generic genesis file path, removing a specific reference to the now-removed x402 demo.

Code Review

This pull request cleanly removes the x402 demo and all associated files from the repository. The changes are extensive but consist almost entirely of deletions, which aligns with the stated goal. The single modification in bin/evd/src/main.rs correctly updates a doc comment to remove a now-invalid path to a demo-specific genesis file, replacing it with a generic placeholder. The changes look good and accomplish the task of removing the demo code.
