The §3 ownership scan classified every ingest-stamped file as replaceable,
so materializing one manifest into a bundle deleted the ingest files another
manifest had stamped there — and removed their index links too.
Narrow ownership to files whose stamp names the running manifest by stem.
The stamp is `{stem}@{sha256[:16]}`; matching on the stem, not the whole
stamp, lets an edited manifest still reclaim the files a prior run of the
same manifest wrote (the stem is stable across content edits), while a
different manifest sharing the bundle keeps its own files. Implements the
trinn-e §10.2 decision. This does not close the operator-copy restriction
(a generated file copied into curated content), which stays documented in
ingest-spec.md:69-72, not enforced.
