Postinstall script referencing TYPES_FILE_PATH doesn't exist

[mannykary]

In the check-types.js postinstall script, this line is referencing a TS file that doesn't exist in the built version of the package. The file that does exist is located at ../esm/types/models.js. The consequence of this issue is that the error is silently failing the postinstall script (and I think in many cases, a lot of users have disabled running postinstall scripts, so they wouldn't even notice this issue).

I was able to confirm this by adding a console.log here, which prints out the following error:

Error: ENOENT: no such file or directory, open '<BASE_PATH>/node_modules/@openrouter/sdk/src/types/models.ts'
    at async open (node:internal/fs/promises:640:25)
    at async readFile (node:internal/fs/promises:1290:14)
    at async main (file:///<BASE_PATH>/node_modules/@openrouter/sdk/scripts/check-types.js:97:23) {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '<BASE_PATH>/node_modules/@openrouter/sdk/src/types/models.ts'
}

(Note: I redacted the actual base path with <BASE_PATH> but left the relative path in).

Changing the path to ../esm/types/models.js fixed the issue and printed the warning message as expected:

$ node scripts/check-types.js
