The infra#179 partial_failure message and the tool descriptor told callers to
"Finalize locally with `hyperguild new-project`" — but that command does not
exist (the hyperguild CLI only has tier/brain/mode; it was specced, never built).
It pointed users at a dead end.
Extracted the message into a pure infra179FinalizeMessage() and reworded it to
name the actual remaining work — cloning the repo and substituting the leftover
__PROJECT_NAME__ / __MODULE_PATH__ placeholders, or retrying — with no reference
to any scaffolding CLI. Descriptor updated to match. Unit-tested the wording.
