chore: remove "type": "module" from @dbml/core

[huydo862003]

Summary

• Remove "type": "module" from @dbml/core package.json to fix CJS consumer type resolution.

• Details:

  • Consuming CommonJS apps (with moduleResolution: "node16" or "nodenext", like Runsql) fail to import this package with the following error:

  The current file is a CommonJS module whose imports will produce 'require' calls; however, the referenced file is an ECMAScript module and cannot be imported with 'require'.

• Context:

  • Our package builds to .mjs and .cjs code files, but .d.ts type declaration files.

• Root cause:

  • TypeScript determines the module kind of .d.ts files using the nearest package.json's "type" field.
  • With "type": "module" set, our index.d.ts is treated as ESM.
    -> TypeScript refuses to let CJS consumers require the type declaration files, even though the runtime entry point (index.cjs) is perfectly valid CJS.

• Solution: Remove "type": "module" from package.json. This makes .d.ts default to CJS, which works for both consumers:

  • CJS consumers: TypeScript sees .d.ts as CJS -> require works
  • ESM consumers: ESM allows importing CJS types -> import works

This is safe because our runtime files already use explicit extensions (.mjs / .cjs), so Node resolves them correctly regardless of the "type" field.
