Change

I added an option storeToHistory to the interface IChatAcceptInputOptions, and set it to true in SendToNewChatAction.run(). In this way, even if the message to be sent to new chat session is automatically inputted by the system, it will be stored into the history as expected.

Pull request overview

This PR fixes an issue where the chat input history stack position was not being reset after starting a new chat session using the "Send to New Chat" action (Ctrl+Shift+Enter). The root cause was that when the input text was programmatically re-submitted to a cleared chat session, it wasn't being stored in the history, which prevented the history cursor from resetting to the end position.

Key Changes

• Added forceStoreToHistory option to IChatAcceptInputOptions interface to allow forcing input storage in history
• Modified the history storage logic to honor this new option even for programmatic queries
• Updated SendToNewChatAction to use this option when re-submitting input to a new chat session

File	Description
src/vs/workbench/contrib/chat/browser/chat.ts	Added optional forceStoreToHistory property to IChatAcceptInputOptions interface
src/vs/workbench/contrib/chat/browser/chatWidget.ts	Updated _acceptInput to check forceStoreToHistory option when determining whether to store input in history
src/vs/workbench/contrib/chat/browser/actions/chatExecuteActions.ts	Modified SendToNewChatAction to pass forceStoreToHistory: true when re-submitting input to new chat

The fix is well-targeted and follows the existing pattern. The ChatHistoryNavigator.append() method (lines 240-247 in chatWidgetHistoryService.ts) resets _currentIndex to the end of history, which solves the reported issue. The changes are minimal and don't affect other parts of the codebase.

Looks like a formatting failure:

[hygiene                  ] src/vs/workbench/contrib/chat/browser/chatWidget.ts(2337,1): Bad whitespace indentation
[hygiene                  ] File not formatted. Run the 'Format Document' command to fix it: src/vs/workbench/contrib/chat/browser/chatWidget.ts

Hm, looks like one still remains

[hygiene                  ] src/vs/workbench/contrib/chat/browser/chatWidget.ts(2338,1): Bad whitespace indentation
[hygiene                  ] File not formatted. Run the 'Format Document' command to fix it: src/vs/workbench/contrib/chat/browser/chatWidget.ts

if you open the file in vscode you should be able to ctrl+shift+p > Format Document to apply formatting

It should be ok now
