[macOS] Deleting forum topic shows "Start" button that wipes all bot conversation threads and data

[daniilos]

Steps to reproduce
Steps to Reproduce:

Open a bot chat with multiple active forum topics/threads (I had 10 threads)
Delete one specific thread from the left sidebar
The right panel clears and shows a blue "Start" button
Click on the "Start" button
Expected behaviour
After deleting a single thread, the interface should either:
Show another existing thread, or
Display an empty state without interactive buttons, or
Return to the main chat view
The "Start" button should NOT appear in this context
Other threads should remain intact

Actual behaviour
After deleting one thread, a blue "Start" button appears in the right panel (similar to first-time bot initialization)
Clicking "Start" triggers /start command which:
Deletes ALL remaining threads with the bot
Wipes all conversation history and data
Resets the bot to initial state
