Garry Tanandcapy-ai[bot] 549b9a8660 fix(ship): finish takes a landed stack parent as the reviewed base, fail-closed (GST-1399) (#4021)
* fix(ship): finish takes a landed stack parent as the reviewed base, fail-closed on metadata and never bounded (GST-1399)

Ported from #4013 onto #4020's route: the stacked-parent path judges every
shipped path's metadata class against main, counts stamp_paths and
release_outputs only while stamp-only, and never feeds the bounded route.
The receipt carry's landed-parent search finds a squash main edited since.

* fix(ship): a loop exception starts at the landed parent; a conflicted base commit never holds a parent (GST-1399)

* fix(ship): a metadata-only conflict still holds a landed parent; a post-merge loop head starts at its own fork (GST-1399)

heldBy counts a merge as conflicted only when a conflicted path is inside its pathspec, so a train's VERSION restamp
in the squash no longer hides the landed parent. The review-loop exception's atHead uses patchBase, so a fix-check head
after the child merged main starts at its own merge base, not at the parent.

* test(ship): stacked-parent loop-exception matrix over merge order, parent state and fix-check head (GST-1399)

28 cells: the child merged main before the parent landed, after, or never; the parent landed by squash, by squash
with a later main edit of its lines, with a release fold, or not at all; the fix-check head is before any merge, the
merge, or after it. Every cell runs the postinstall and stamp_paths probes (parent changes main never took, edited
after the fix-check) and a control run (the child's own file and a main-only file edited after the fix-check).

Red at 3f4c47c (4): merged before or after the landing × parent edited × fix-check head merge or post; the
exception accepts package.json and src/policy.ts. The other 24 cells pass.

* fix(ship): a loop exception's fix-check paths are the head's own patch from both forks; heldBy reads merge-tree with -z (GST-1399)

The "touched at the fix-check head" set is the intersection of the head's patch from its merge base and from the
landed parent, so neither a parent change main never took nor a main-only file counts as reviewed, whatever order
the child merged main in. heldBy reads conflicted names NUL-separated, so a C-quoted name still counts as a conflict.
The stacked-parent matrix (28 cells) is green.
