chore: migrate axios to fetch

[yifancong]

Summary

This pull request removes the dependency on axios across multiple packages and refactors all HTTP requests to use the native fetch API (with a fallback to undici for Node.js environments). It introduces utility functions to handle fetch requests, updates all relevant code to use these utilities, and adds tests for the new request logic. Additionally, it updates build configurations to reflect the removal of axios and ensures proper handling of Node.js built-in modules in the client build.

These changes collectively simplify the codebase, reduce dependencies, and improve compatibility across environments by standardizing on the fetch API for HTTP requests.

• After removing axios, @types/node-fetch appears unused (no node-fetch imports/references found in packages/core). Since @types/node already provides fetch typings on modern Node, consider removing @types/node-fetch to avoid carrying an extra (now stale) types package.
