MCP tool search and safer PowerShell handling land in stable 0.142.2
The 0.142.2 patch improves MCP discovery, plugin presentation, and Windows command-safety checks.
This patch is broader than a typical point release. Developers get search-first MCP discovery, plugins gain dark-mode asset metadata, and PowerShell commands that the safety classifier cannot fully inspect now require approval.
