docs(audits): measure whether os create and os init should converge (#15531)

The measurement #14824's ruling reserved. No emitted output, no published
export and no command surface changed — the convergence decision stays the
maintainer's.

Rendered both command bodies into throwaway trees and hashed the results:
of the four file names both emit, two already render byte-identical output;
the genuine duplicate is one template (`os create example`), not a command
family. Three scaffolders ship, not two — `npx create-objectstack` carries
13 doc pages to `os create`'s 4 and `os init`'s 3.
