docs: improve English clarity and natural flow in documentation

[Copilot]

Overview

This PR improves the English documentation in 8 files to make them read more naturally and professionally. Many paragraphs were originally translated from Chinese and contained phrasing that, while technically correct, didn't sound like authentic English.

What Changed

Improved documentation in the following files:

• guide/basic/server.mdx - Dev server functionality and middleware integration
• guide/framework/react.mdx - React Compiler and hot reload sections
• guide/configuration/rsbuild.mdx - Config file loading and export functions
• guide/start/quick-start.mdx - Setup instructions
• guide/advanced/browser-compatibility.mdx - Polyfills and transpilation explanations
• guide/basic/output-files.mdx - Asset handling descriptions
• guide/advanced/browserslist.mdx - Browser configuration examples
• guide/basic/static-assets.mdx - Static asset handling

Examples of Improvements

Key Changes

• Replaced verbose phrasing with concise, natural English
• Changed passive to active voice where appropriate ("can be accessed" → "you can access")
• Simplified complex structures for better readability
• Used contractions where natural ("will not" → "won't")
• Streamlined conditionals ("If you want to skip" → "To skip")

What Didn't Change

• ✅ No meaning changes - All technical content preserved exactly
• ✅ No structural changes - Same sections, headings, and organization
• ✅ No code changes - All code examples remain identical
• ✅ Chinese docs unchanged - Chinese is the original source

Testing

• ✅ Prettier formatting passes
• ✅ Heading case linting passes (sentence case maintained)
• ✅ Spell checking passes
• ✅ Code review completed with no issues

Notes

This PR stays under the 10-file limit as requested. The changes are minimal and surgical, focused only on improving readability while maintaining technical accuracy and consistency with high-quality open-source documentation standards.

Original prompt

Improve the English docs in website/docs/en. Many paragraphs were
translated from Chinese and may sound unnatural.

  Rewrite sentences that don't read like authentic, professional English —
  **without changing their meaning** — so they match the tone of
  high-quality open-source docs.


  - **IMPORTANT:** Only change a sentence if it clearly improves clarity or
  correctness.

  - **IMPORTANT:** Don't alter the original meaning.

  - If you edit files in `docs/en`, check the same files in `docs/zh` to see
  if similar updates are needed.

  - Use clear, simple language for non-native English readers.

  - Keep reasonable technical abbreviations (e.g., `dev server`).

  - Use sentence case for Markdown headings.

  - Don't change more than 10 files in one PR.

  - Start PR titles with `docs:`
