This commit fixes a potential AttributeError in ChatStreamManager.__init__().
Problem:
- When checkpoint_saver=True and db_uri=None, the code attempts to call
self.db_uri.startswith() on line 56, which raises AttributeError
- Line 56: if self.db_uri.startswith("mongodb://"):
This fails with "AttributeError: 'NoneType' object has no attribute 'startswith'"
Root Cause:
- The __init__ method accepts db_uri: Optional[str] = None
- If None is passed, self.db_uri is set to None
- The code doesn't check if db_uri is None before calling .startswith()
Solution:
- Add explicit None check before string prefix checks
- Provide clear warning message when db_uri is None but checkpoint_saver is enabled
- This prevents AttributeError and helps users understand the configuration issue
Changes:
```python
# Before:
if self.checkpoint_saver:
if self.db_uri.startswith("mongodb://"):
# After:
if self.checkpoint_saver:
if self.db_uri is None:
self.logger.warning(
"Checkpoint saver is enabled but db_uri is None. "
"Please provide a valid database URI or disable checkpoint saver."
)
elif self.db_uri.startswith("mongodb://"):
```
This makes the error handling more robust and provides better user feedback.

- Backend: add citation format to lead_agent and general_purpose prompts
- Add CitationLink component (Badge + HoverCard) for citation cards
- MarkdownContent: detect citation: prefix in link text, render CitationLink
- Message/artifact/subtask: use MarkdownContent or Streamdown with CitationLink
- message-list-item: pass img via components prop (remove isHuman/img)
- message-group, subtask-card: drop unused imports; fix import order (lint)

- Keep upstream subagent HARD LIMIT (max 3 task calls, batching) in subagent_reminder
- Keep our removal of Citations: do not add back 'Citations when synthesizing'

Citations:
- In shouldShowCitationLoading, treat any unreplaced [cite-N] in cleanContent
as show-loading (no body). Fixes Ultra and other modes when refs arrive
before the <citations> block in the stream.
- Single rule: hasUnreplacedCitationRefs(cleanContent) => true forces loading;
then isLoading && hasCitationsBlock(rawContent) for streaming indicator.
SSE end state:
- When stream finishes, SDK may set isLoading=false before client state has
the final message content, so UI stayed wrong until refresh.
- Store onFinish(state) as finalState in chat page; clear when stream starts.
- Pass messagesOverride={finalState.messages} to MessageList when not loading
so the list uses server-complete messages right after SSE ends (no refresh).
Chore:
- Stop tracking .githooks/pre-commit; add .githooks/ to .gitignore (local only).

fix(前端): 杜绝半成品引用，SSE 结束时展示正确状态
引用：
- shouldShowCitationLoading 中只要 cleanContent 仍含未替换的 [cite-N] 就
只显示加载、不渲染正文，解决流式时引用块未到就出现 [cite-1] 的问题。
- 规则：hasUnreplacedCitationRefs(cleanContent) 为真则一律显示加载；
此外 isLoading && hasCitationsBlock 用于流式时显示「正在整理引用」。
SSE 结束状态：
- 流结束时 SDK 可能先置 isLoading=false，客户端 messages 尚未包含
最终内容，导致需刷新才显示正确。
- 在对话页保存 onFinish(state) 为 finalState，流开始时清空。
- 非加载时向 MessageList 传入 messagesOverride={finalState.messages}，
列表在 SSE 结束后立即用服务端完整消息渲染，无需刷新。
杂项：
- 取消跟踪 .githooks/pre-commit，.gitignore 增加 .githooks/（仅本地）。

Strengthen the SUBAGENT_SECTION prompt to prevent the model from launching
more than 3 subagents in a single response. When >3 sub-tasks are needed,
the model is now explicitly instructed to plan and execute in sequential
batches of ≤3. Reinforced at three prompt injection points: thinking style,
main subagent instructions, and critical reminders.

Add two new middlewares to improve robustness of the agent pipeline:
- DanglingToolCallMiddleware injects placeholder ToolMessages for
interrupted tool calls, preventing LLM errors from malformed history
- SubagentLimitMiddleware truncates excess parallel task tool calls at
the model response level, replacing the runtime check in task_tool
