SpecStory Extension Overwrites Previous Chat History Files on New GitHub Copilot Chat Session Initialization

[ahsancloudcode]

Bug Description
In the SpecStory extension for VSCode, inside the .specstory folder, there is a history folder where chat history from GitHub Copilot Chat prompts is saved as .md files. However, when opening a new chat via the plus button in GitHub Copilot Chat and entering new prompts, the extension creates a new .md file but replaces the old .md history file instead of preserving it. This means the previous chat history file is deleted or overwritten.

To Reproduce

Open VSCode with the SpecStory extension installed.

Use GitHub Copilot Chat and enter some prompts. The chat history gets saved as .md files inside .specstory/history.

Click the plus button in GitHub Copilot Chat to open a new chat.

Enter new prompts. A new .md file is created but the previous .md file is overwritten or replaced.

Expected behavior

Each chat session should create a unique .md history file. Opening a new chat or clearing chat history should not delete or replace existing .md history files. All previous chat histories should remain intact and accessible.
