Upstream's update added telemetry that is on by default. Sets the three
opt-out env vars on the blender server in .mcp.json, which also suppresses
the consent prompt it would otherwise raise through the MCP client.
Documents the addon-side 'Allow Telemetry' preference as a separate switch:
it defaults to on, covers prompts, code snippets, screenshots and trajectory
data, and lives inside Blender where these env vars cannot reach it.
Both mcp/godot-mcp and mcp/blender-mcp were already cloned locally and
registered in .gitmodules/.mcp.json/CLAUDE.md, but neither submodule's
gitlink had actually been committed, so a fresh clone wouldn't pull
either down. Stages the two gitlinks so `git submodule update --init
--recursive` works as documented.
