Subject: [PATCH] fix(engine-image): add curl for Shell scheduler tasks (Closes
 #12)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Shell nodes commonly call HTTP APIs via curl (webhooks, pipeline
executor endpoints, ad-hoc smoke tests). Without it, every shell flow
that touches HTTP needs to either install curl at runtime or fall back
to wget — neither is a good first impression.

curl adds ~1.4 MiB to the image (alpine package), which is below the
noise threshold of the existing Python + Node + Docker CLI runtime
bundle (~80 MiB combined).
