Project layouts carry .gitignore files as payload for generated projects,
but git treats any nested .gitignore as live configuration scoped to its
directory - the templates self-censor, silently untracking their own
content in the outer repo (discovered via the git/fossil tracked-set
verification; stopgap force-adds in fc1c474c). G-012 [proposed] requires
payloads stored inert (neutral rename or fauxlink-encoded - mechanism an
implementation decision recorded in the detail file) with materialization
at project generation, plus a punkcheck-tracked make.tcl template-refresh
step generalising the existing sync_layouts (which covers only
build.tcl/make.tcl into custom/_project) to the vendor/punk layout base
and derived payloads. Acceptance covers a provably-inert nested-rule scan,
generated-project content equivalence, a working refresh after a
canonical-source edit, and retiring the per-file force-add exceptions.
