build is the direct-mode write command.
tbl__* and mv__* names, and replays retained history through the rebuilt graph.
Before writing, StreamBuild displays the destructive plan and asks:
y or yes approves. --auto-approve skips the prompt. JSON execution requires
--auto-approve.
The selected model or pipeline includes all downstream models. A full build runs every audit; a
selected build runs audits whose complete model reference set is in execution scope.
