docs: add cli docs

[gene9831]

• 添加CLI介绍文档（移除了之前的CLI旧文档）
• 快速开始里面，增加了推荐使用 CLI 的 tip
• 顺便修复了一个 @opentiny/vue-theme 样式覆盖的问题
  实际上就是 Layout 组件的 class 类名匹配到了 @opentiny/vue-theme 的一个选择器，导致很多样式变成 @opentiny/vue-theme 的样式了

Walkthrough

This PR reorganizes CLI documentation by creating a comprehensive new CLI integration guide, promotes CLI usage throughout the quick-start guide, updates navigation to expose the new guide, and performs minor CSS class cleanup on the layout component.

CLI guide and quick-start—now you see!

In `@docs/src/guide/cli-integration.md`:
- Around line 118-125: The heading "API_KEY" is ambiguous compared to the
example env var; update the text in cli-integration.md to explicitly name and
use a single environment variable (VITE_DEEPSEEK_API_KEY) everywhere: replace
the generic heading "API_KEY" with "VITE_DEEPSEEK_API_KEY" (or add a clarifying
sentence "Use VITE_DEEPSEEK_API_KEY as generated by the CLI"), ensure the
example shows VITE_DEEPSEEK_API_KEY=your_api_key and add one line stating "The
CLI-generated key must be set in VITE_DEEPSEEK_API_KEY" so the variable name is
unique and unambiguous.
