LofiSu 4f9d1d524e feat(frontend): unify citation logic and prevent half-finished citations
- Add SafeCitationContent as single component for citation-aware body:
  useParsedCitations + shouldShowCitationLoading; show loading until
  citations complete, then render body with createCitationMarkdownComponents.
  Supports optional remarkPlugins, rehypePlugins, isHuman, img.

- Refactor MessageListItem: assistant message body now uses
  SafeCitationContent only; remove duplicate useParsedCitations,
  shouldShowCitationLoading, createCitationMarkdownComponents and
  CitationsLoadingIndicator logic. Human messages keep plain
  AIElementMessageResponse (no citation parsing).

- Use SafeCitationContent for clarification, present-files (message-list),
  thinking steps and write_file loading (message-group), subtask result
  (subtask-card). Artifact markdown preview keeps same guard
  (shouldShowCitationLoading) with ArtifactFilePreview.

- Unify loading condition: shouldShowCitationLoading(rawContent,
  cleanContent, isLoading) is the single source of truth. Show loading when
  (isLoading && hasCitationsBlock(rawContent)) or when
  (hasCitationsBlock(rawContent) && hasUnreplacedCitationRefs(cleanContent))
  so Pro/Ultra modes also show "loading citations" and half-finished
  [cite-N] never appear.

- message-group write_file: replace hasCitationsBlock + threadIsLoading
  with shouldShowCitationLoading(fileContent, cleanContent,
  threadIsLoading && isLast) for consistency.

- citations/utils: parse incomplete <citations> during streaming;
  remove isCitationsBlockIncomplete; keep hasUnreplacedCitationRefs
  internal; document display rule in file header.

feat(前端): 统一引用逻辑并杜绝半成品引用

- 新增 SafeCitationContent 作为引用正文的唯一出口:内部使用
  useParsedCitations + shouldShowCitationLoading,在引用未就绪时只显示
  「正在整理引用」,就绪后用 createCitationMarkdownComponents 渲染正文;
  支持可选 remarkPlugins、rehypePlugins、isHuman、img。

- 重构 MessageListItem:助手消息正文仅通过 SafeCitationContent 渲染,
  删除重复的 useParsedCitations、shouldShowCitationLoading、
  createCitationMarkdownComponents、CitationsLoadingIndicator 等逻辑;
  用户消息仍用 AIElementMessageResponse,不做引用解析。

- 澄清、present-files(message-list)、思考步骤与 write_file 加载
  (message-group)、子任务结果(subtask-card)均使用
  SafeCitationContent;Artifact 的 markdown 预览仍用同一 guard
  shouldShowCitationLoading,正文由 ArtifactFilePreview 渲染。

- 统一加载条件:shouldShowCitationLoading(rawContent, cleanContent,
  isLoading) 为唯一判断。在「流式中且已有引用块」或「有引用块且
  cleanContent 中仍有未替换的 [cite-N]」时仅显示加载,从而在 Pro/Ultra
  下也能看到「正在整理引用」,且永不出现半成品 [cite-N]。

- message-group 的 write_file:用 shouldShowCitationLoading(
  fileContent, cleanContent, threadIsLoading && isLast) 替代
  hasCitationsBlock + threadIsLoading,与其他场景一致。

- citations/utils:流式时解析未闭合的 <citations>;移除
  isCitationsBlockIncomplete;hasUnreplacedCitationRefs 保持内部使用;
  在文件头注释中说明展示规则。
