Add documentation and showcase examples for all plugins

[Copilot]

Problem

Plugins were inconsistently documented: plugin-editor and plugin-markdown lacked showcase examples, plugin-object lacked documentation. The CLI also didn't auto-import plugins, causing registration failures.

Changes

Added Showcase Examples

• code-editor.json: Monaco editor demonstrations (JavaScript, TypeScript, Python, JSON, HTML) with theme variants and read-only mode
• markdown.json: GFM rendering examples (headings, tables, code blocks, task lists, blockquotes)

Added Documentation

• plugin-object.md: Complete reference for ObjectTable, ObjectForm, and ObjectView with TypeScript types and ObjectQL integration examples

Fixed Plugin Loading

// packages/cli/src/utils/app-generator.ts
import '@object-ui/components';
import '@object-ui/plugin-charts';
import '@object-ui/plugin-editor';
import '@object-ui/plugin-kanban';
import '@object-ui/plugin-markdown';
import '@object-ui/plugin-object';  // Now auto-imported

// packages/cli/src/commands/dev.ts
viteConfig.resolve.alias = {
  '@object-ui/plugin-charts': join(cwd, 'packages/plugin-charts/src/index.tsx'),
  '@object-ui/plugin-editor': join(cwd, 'packages/plugin-editor/src/index.tsx'),
  '@object-ui/plugin-kanban': join(cwd, 'packages/plugin-kanban/src/index.tsx'),
  '@object-ui/plugin-markdown': join(cwd, 'packages/plugin-markdown/src/index.tsx'),
  '@object-ui/plugin-object': join(cwd, 'packages/plugin-object/src/index.ts'),  // Correct .ts extension
};

Updated Showcase Navigation

Added "Code Editor" and "Markdown" menu items to Complex section in app.json.

Result

All 5 plugins now have complete documentation and working showcase demonstrations.

Original prompt

所有的插件也应该在文档中、演示效果。
