gmgn-cli crashes on Node 18 despite engines.node advertising >=18.0.0

[deepfeature]

Summary

package.json currently advertises Node >=18.0.0, but the dependency set includes undici@^7.24.1, which requires Node >=20.18.1.

As a result, the CLI crashes on Node 18 before it can execute a request.

Relevant source:

• package.json: "undici": "^7.24.1"
• package.json: "engines": { "node": ">=18.0.0" }

Reproduction

Environment:

• Node v18.16.1
• npm 9.5.1

Steps:

1. Run npm ci
2. Run npx --no-install tsx src/index.ts market trending --chain sol --interval 1h --limit 10 --raw

Actual behavior

The command crashes with:

/Users/.../node_modules/undici/lib/web/webidl/index.js:537
webidl.is.File = webidl.util.MakeTypeAssertion(File)
                                               ^

ReferenceError: File is not defined

Expected behavior

One of the following should be true:

• the package works on Node 18 as declared, or
• the supported Node version is raised in package.json and documentation to match the actual runtime requirement.

Suggested fixes

• Pin undici to a Node-18-compatible version, or
• Raise the minimum supported Node version to 20.18.1+ and update the docs/examples accordingly.
