Summary

Prepare Desktop v0.16.0, bringing together the merged workspace, image attachment, agent collaboration, file lookup, and Ollama model-browser improvements.

For example, a user can keep separate projects in different workspaces, attach screenshots to a vision-enabled conversation, and discover or pull another model from inside Desktop.

What changed

• Set the application version to 0.16.0.
• Move the accumulated Unreleased changelog into 0.16.0, dated November 11, 2026, with a short user-facing introduction.
• Add curated release notes covering workspaces, image attachments, model discovery, mentions, collaboration, other fixes, and installation.
• Retain the published MandoCode CLI v0.16.2 engine pin (1087b8a) already merged in PR Feature: browse and pull Ollama models in Desktop #88.
