Current and expected behavior

The package.json file contains mistakes with regards to the types -> it shouldn't.

Environment

System:
    OS: Linux 6.18 Nobara Linux 43 (KDE Plasma Desktop Edition)
  Binaries:
    Node: 24.13.1 - /home/rebec/.nvm/versions/node/v24.13.1/bin/node
    npm: 11.10.0 - /home/rebec/dev/eslint-plugin-functional/node_modules/.bin/npm
    pnpm: 10.30.1 - /home/rebec/.nvm/versions/node/v22.15.0/bin/pnpm
  npmPackages:
    @babel/eslint-parser: 8.0.0-rc.2 => 8.0.0-rc.2 
    eslint: 10.0.1 => 10.0.1 
    rollup: 4.58.0 => 4.58.0 

Possible solution

Current package.json contains:

"types": "./types.d.ts",
"exports": {
  ".": {
    "default": "./lib/index.js",
    "types": "./types.d.ts"
  },
  "./package.json": "./package.json"
},

But it should be:

"types": "./types.d.cts",
"exports": {
  ".": {
    "types": "./types.d.cts",
    "default": "./lib/index.js"
  },
  "./package.json": "./package.json"
}

The difference being the filename of the types file (the file that exists ends with .d.cts, not .d.ts) and that the default property needs to be declared last.
