Fix: Remove broken zlib dependency and fix ESM import order

- Remove zlib npm package from dependencies. The code uses Node.js
  built-in zlib module, not the npm package. The npm zlib package
  uses deprecated node-waf and fails to install on modern systems.

- Fix import order in index.ts. The default export must come after
  the import statement to prevent "Cannot access before initialization"
  error when compiled to CommonJS.
