fix(create-sdk): keep --json stdout pure NDJSON

Browse Source 
The SKILL.md contract says every stdout line is one JSON event, but
createProject wrote the Created/Next-steps templates to stdout and the
default install/build path inherited the launcher's stdio, so package-
manager child output interleaved with the event stream. Under --json,
route human progress to stderr and run install/build through a
NodeCommandRunner that redirects child stdout+stderr to stderr.
