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.
dsh-sdk create <source> adds a github (github:owner/repo#ref) or npm (pkg@version)
plugin as a package-manager-native dependency, then mounts the resolved dependency
in cordis.yml through ProjectEditSession. Adds PackageManager.add(spec) and
ProjectEditSession.addExternalPlugin(id, packageName). No giget/pacote. Per-file
100% coverage on the new/changed files.
