Heads-up: Update both addon and solver to avoid "Protocol Mismatch"

[ryichando]

The Blender addon can auto-update from the extensions platform, but the solver binary (Windows bundle / Docker image) does not auto-update with it. If only one side updates, the addon may refuse to connect and show a "Protocol Mismatch" error. The same can happen in reverse if you update the solver binary while keeping the older addon.

Whenever you update one side, update the other too:

• Solver: grab the latest Windows bundle from the GitHub Releases page, or pull the latest Docker image from GHCR.
• Blender addon: update to the latest on the Blender extensions platform. If the remote repository doesn't auto-update, or a fresh install from the remote repository
  still gives you the mismatch, download the latest addon zip from the GitHub Releases page and install it from disk instead.

Note: the three artifacts (Windows, Docker, Blender extension) are published by separate pipelines, so right after a release there can be a short window where one side isn't out yet. If only one shows a newer version, wait a bit for the other, then update both.
