[Bug] Opening threads creates Inbox drafts when “Keep addressed agents active” is enabled

[skyerus]

Describe the bug

In Buzz Desktop v0.5.0, opening a thread causes that thread to appear as a draft in the Inbox view when Keep addressed agents active is enabled. No message needs to be typed or edited: clicking into a thread is enough. Repeating this across threads fills Inbox with drafts for every thread visited.

This appears to be a regression in the latest release.

Steps to reproduce

1. Install or update to Buzz Desktop v0.5.0.
2. Enable Settings → Keep addressed agents active.
3. Open the Inbox view.
4. Click into any thread without typing a message.
5. Return to Inbox.
6. Observe that the opened thread is now listed as a draft.
7. Repeat with other threads; each visited thread becomes a draft.

Expected behavior

Opening or viewing a thread should not create a draft. A thread should appear as a draft only after the user enters or changes unsent message content. Preselecting addressed agents should not count as draft content by itself.

Version and platform

• Buzz version: v0.5.0
• OS: unknown

Logs / additional context

The behavior is triggered by this setting:

Keep addressed agents active
Keep agents you address selected for future messages in the same channel or thread. Remove them from the composer at any time.
