Subject: Implement smarter AI chat window detection to reuse existing AI chat
 windows.

First search for AI chat windows within the same tab and then within other tabs if none are found in the current tab.
It now prioritizes the reusing of an existing chat window that matches the '.aichat' filetype before considering opening a new one.
If there are no existing AI chat windows, the plugin will open a new chat window as a last resort.

-      "  reuse chat in active window or tab
+      " TODO: look for first active chat buffer. If .aichat file is used,
