Assistant window shows a “A new version of Assistant is available” log with an update prompt when the Assistant package is already updated

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Open the Package Manager window
3. Install the AI Assistant package (com.unity.ai.assistant)
4. Open the "Version History" tab for the Assistant package
5. Downgrade the Assistant package to any lower version (1.6.0-pre.1 for example)
6. Update the Assistant package to the newest version (2.0.0-pre.1)
7. Open the Assistant window (Window > AI > Assistant)
8. Observe the Assistant window

Actual results: “A new version of Assistant is available” log with an update prompt is shown

Expected results: No update log is shown since the Assistant is already newest version

Reproducible with versions: 2.0.0-pre.1 (6000.0.70f1, 6000.3.11f1, 6000.4.0b12, 6000.5.0a8)

Tested on (OS): MacOS Silicon Tahoe 26.2

Notes:

• Make sure to use an organization that has points since the update log does not show when there are no points in the organization
