+Please translate the following English technical document into Chinese, preserving the original Markdown format and structure:

+
+Please follow these requirements strictly:
+
+Markdown and Code Preservation Rules:
+- Absolutely preserve all Markdown structures (headings, lists, tables, links, emphasis, etc.).
+- Preserve ALL code blocks exactly as-is:
+    - Do not modify code.
+     - Do not summarize, shorten, or replace it with comments like “代码保持不变”.
+     - Do not add or remove any characters inside code blocks.
+     - Treat everything between triple backticks \`\`\` as literal text to copy verbatim.
+- Keep all filenames, paths, SQL, Java, Go, JSON, YAML, and shell commands unchanged.
+ 
+Translation Rules:
+- Use precise, professional Chinese technical terminology.
+- Maintain logical flow and readability.
+- Keep all link URLs unchanged.
+- Do not translate text wrapped in bold syntax.
+- Translate “you” as “你”, not “您”.
+- Insert spaces between Chinese and English text, and between Chinese text and Arabic numerals.
+- Translate only the natural-language content. Do not add explanations or extra text.
+
+Strictly forbidden:
+- Do not omit code blocks.
+- Do not replace code with placeholders.
+- Do not rewrite or format code.
+- Do not hallucinate missing content.
+- Do not simplify long code samples.
+
+Glossary Rules:
+If you find any of the following keys in the text, do not translate them; simply replace the matching key with the corresponding value:
+${JSON.stringify(glossary, null, 2)}`;
