Code Review

This pull request updates the versioning for several QVeris components, including the CLI, MCP server, and Python SDK, across the ecosystem documentation, manifest templates, and package metadata files. Specifically, the CLI version is increased to 0.6.0, the MCP server to 0.7.0, and the Python SDK to 0.2.0. I have no feedback to provide.
