docs(lark-doc): add table intelligence guidelines for standard table vs sheet

[jiezhengj]

Summary

Establishes table intelligence guidelines in Lark Docx XML, standardizing the selection boundary between native document tables (<table>) and embedded spreadsheets (<sheet>) and clarifying cell nesting capabilities.

Key Enhancements

1. Standard Document Table (<table>) as Default:

   • Standard XML tables (<table>) are the default choice for static data presentation, rule comparisons, timetables, and structured listings.
   • Recommends background-color="light-gray" on all <th> header cells to maintain a clean, breathable layout.
   • Clarifies full support for inline rich text (including <br/>, <b>, <code>) inside <td> cells.

2. Spreadsheet (<sheet>) Selection Boundary & Cell Nesting:

   • Embedded sheets are selected as the primary table format only when cell formula calculations (starting with =) or multi-sheet workbooks are strictly required.
   • Clarifies that in complex reporting scenarios, native table cells (<td>) fully support nesting embedded <sheet> resource blocks (e.g. <td><sheet type="blank"></sheet></td>).

Tested and validated across document imports.

Summary by CodeRabbit

明确 <sheet> 是否可以嵌套在 <table> 中。

Line 51-52 的“仅当……使用 <sheet>”容易被理解为禁止在原生表格单元格中嵌套 <sheet>。但提供的下游测试 shortcuts/doc/docs_fetch_im_markdown_test.go 已验证 <td><sheet ...></sheet></td> 的转换。请确认这是受支持的组合，并在此处说明该规则是选择主要表格形态，或补充嵌套示例。
