Update Wording Rule

Add a new wording rule to all 4 vocabulary-rule.md files in the w repo.

Target Files

All 4 files must be updated identically:

• $HOME/repos/w/cg/doc/src/content/docs/overview/vocabulary-rule.md
• $HOME/repos/w/esa/doc/src/content/docs/overview/vocabulary-rule.md
• $HOME/repos/w/message/doc/src/content/docs/overview/vocabulary-rule.md
• $HOME/repos/w/zpaper/doc/src/content/docs/overview/vocabulary-rule.md

The cg, esa, and zpaper paths follow the doc/src/content/docs/overview/ layout used by the apply-voice skills and writer agents (the sites migrated to the Astro/zudo-doc layout). The w/message repo's layout could not be verified from this environment — it is assumed to have migrated to the same layout, so confirm its vocabulary-rule.md path before appending.

Process

1. Read the argument to understand the new rule. Expect format like:

   ふうに should be 風に
   
   そういうふうに → そういう風に
   そういうふうな → そういう風な
   

   The first line is the rule summary. Following lines are examples.

2. Read one of the target files to understand current structure and the last rule entry.

3. Compose a new rule section matching the existing format. Each rule section has:

• ### heading with the word pair (e.g., ### 「ふうに」と「風に」)
• One-sentence explanation of when to use which form
• Markdown code block with <!-- ✅ Good --> and <!-- ❌ Bad --> examples
• **判断基準:** section with bullet points summarizing the decision criteria

4. Append the new section to the end of each target file. Use the Edit tool on all 4 files.

5. Report what was added.

Example Output Section

For a rule "ふうに should be 風に":

### 「風に」と「ふうに」

「風に」「風な」と漢字で表記する。「ふうに」「ふうな」とひらがなで書かない。

\`\`\`markdown
<!-- ✅ Good -->

そういう風に考えると、別の方法が良いかもしれません。
そういう風な書き方をする場合は注意が必要です。

<!-- ❌ Bad -->

そういうふうに考えると、別の方法が良いかもしれません。
そういうふうな書き方をする場合は注意が必要です。
\`\`\`

**判断基準:**

- 「〜風に」「〜風な」「〜風だ」→ 漢字「風」を使用

Important

• Keep the existing frontmatter and content intact
• The new rule is appended at the end of the file
• All 4 files must have identical content after the update
• Write the explanation and examples in Japanese
• If the user provides examples, use them. If not, generate appropriate ones
