feat: Lint plugin POC

[aleksanderkatan]

This is an eslint plugin, thus it should be compatible with oxc.
The plugin currently has one rule, which detects int/int divisions.
I did not do any package publishing stuff yet.

To test the CLI locally in the typegpu package:

• run ni; nr build in the lint plugin package,
• run pnpm install -D eslint, pnpm install -D @typescript-eslint/parser in typegpu package,
• add "eslint-plugin-typegpu": "workspace:*" dependency to typegpu dev dependencies in package.json,
• add an eslint.config.js file

import typegpu from 'eslint-plugin-typegpu';
import tsParser from '@typescript-eslint/parser';

export default [
  typegpu.configs.recommended,
  {
    files: ['**/*.ts', '**/*.tsx'],
    languageOptions: {
      parser: tsParser,
    },
  },
];

• run ni; npx eslint in typegpu package.

The plugin tests use vitest's describe and it under the hood, and are compatible with hot reload. Tests are wrapped into a describe to let vitest's static analysis know that this is in fact a test file.

Edit:
I checked and the plugin is compatible with oxlint -- we need to install it and add "jsPlugins": ["eslint-plugin-typegpu"], to the .oxlintrc.json file, as well as list all rules that we want to enable. To my understanding, importing rule presets will become possible after issue oxc-project/oxc#17527 is completed.
