publish_article reverts title changes saved via note_update_article

[katanumahotori]

Summary

When a published article has pending draft edits saved via note_update_article (which uses draft_save?is_temp_saved=true), calling note_publish_article publishes the new body but the old title. The title change is silently lost.

Reproduction

1. Take a published article (e.g. key nXXXX) with title Old Title.
2. note_update_article(article_id, title="New Title", body="new body") → returns success (saved as draft).
3. note_publish_article(article_id=...) → article is published with the new body, but the live page still shows Old Title.

Confirmed on a real note.com article (2026-06-10).

Root cause

In publish_article() (src/note_mcp/api/articles.py), the title is read from data.name first, falling back to note_draft.name only when data.name is empty:

article_title = article_data.get("name", "")
if not article_title:
    note_draft = article_data.get("note_draft")
    ...

For a published article with pending edits, data.name holds the stale published title (truthy), so note_draft.name (the new title) is never used. Note the body logic right below already prefers note_draft.body — the title logic is asymmetric.

Fix

Prefer note_draft.name over data.name, mirroring the body logic. PR with a regression test incoming.
