Inconsistent step numbering: Steps 1-2 show "[X/5]" format, but steps 3-6 show "[X/6]" format. All steps should consistently show the correct total count of 6 steps.

[nitpick] Consider adding UV_HTTP_TIMEOUT=120 to the uv pip install command for consistency with the MCP server Dockerfile.dev (line 18 in packages/mcp-server/Dockerfile.dev). This ensures both services have the same timeout configuration for dependency installation.
