Fix other creator types returned as author

[Xiao-Chenguang]

Author graph include wrong link of other creator types (e.g. editor). This lead to wrong link between papers doesn't share any author but published in the same journal/procceeding as the editors are the same. The error located in the function getAuthors which get more than authors. With one more filter on creator type (author is 8), this could be fixed.

通过在作者抽取逻辑中增加 creatorTypeID 过滤，修复了将编辑等其他角色误当作者导致的错误关联问题，变更小且方向正确。

Warning

⚠️ 使用硬编码 creatorTypeID==8 可维护性差且可能在不同环境/版本下不稳定

当前直接以数值 8 代表“author”进行过滤。该魔法数字缺少语义，后续维护者难以理解；同时若 Zotero 的 creatorTypeID 在不同版本/本地化/数据源下存在差异或扩展（例如不同 itemType 的 creatorTypes），硬编码可能导致作者被误过滤或漏过滤。更稳妥的方式是基于 creatorType（字符串）或通过 Zotero API 查询 author 对应的类型 ID（若可用）。

建议: 将 8 抽成具名常量并添加注释；如有可用 API，优先按 creatorType 字符串/动态查询 author 的 typeID，避免魔法数字散落。

Suggested change

	return item.getCreators().filter(a => a.creatorTypeID == 8).map(a => {
	let getAuthors = (item: Zotero.Item) => {
	// creatorTypeID: 8 means "author" in Zotero creator types
	const AUTHOR_CREATOR_TYPE_ID = 8
	return item.getCreators().filter(a => a.creatorTypeID === AUTHOR_CREATOR_TYPE_ID).map(a => {
	return `${a.firstName} ${a.lastName}`
	})
	}
