Problem Statement

When using Claude in VS Code, the chat history delete button is always enabled with no way to prevent accidental deletions. There should be a user-controlled setting to disable or lock the delete button for chat history.
Use case:
It's easy to accidentally click the delete button and lose valuable conversation history. A toggle in the extension settings to disable the delete button — or require a confirmation step — would give users more control and prevent unintended data loss.

Proposed Solution

Proposed solution:

Add a setting like claude.chatHistory.disableDelete: true/false in VS Code settings
When enabled, the delete button is hidden or grayed out
Optionally, add a confirmation dialog before deletion even when the button is active

Expected behavior:
Users can opt in to locking their chat history from deletion, preserving context across sessions without risk of accidental loss.
