Description

This PR introduces a new ESLint configuration concept that enforces consistent code style and import ordering across the Univer codebase.

Changes

• ESLint Configuration Refactor: Reorganized rules into modular presets with comprehensive documentation
• Import Ordering:
  • Type imports separated from value imports
  • Grouped by source: external → @univerjs → local
  • Added newlines between groups
• Code Style: Fixed comma-dangle, indentation, and end-of-file newlines

Example Import Order

// Type imports
import type { IKeyValue } from '@univerjs/core';

// External packages
import { Disposable, EventSubject } from '@univerjs/core';

// Local alias type imports
import type { IButtonProps } from '@/components/button';

// Local alias imports
import { Button } from '@/components/button';

// Relative type imports
import type { IDragEvent } from './basics/i-events';

// Relative imports
import { CURSOR_TYPE } from './basics/const';
