Pine UDT object graphs on the paged object Store - #586

Brings in the store branch head after its merge of main. No conflict: the
store branch's new changes touch the workflow files, the CI preflight script
and its self-test, and the CI documentation, none of the lines this branch
edits.

The fragment under tests/cr150.d carried the name of the work package that
introduced it. It is renamed after what it registers, and the comments in the
slow-test pin list that cite its path follow. The registration file is picked
up by the existing glob, so no CMake line changes; the content of the fragment
is unchanged.

The kernel source block of CMakeLists.txt is read line by line by the
detached-comments measurement, which takes each line as one path. The
UDT graph source shared a line with the object store source, so the
measurement stopped at "kernel source is missing". Give it its own line
and move the doc citations of the top-level build file that follow the
inserted line by one.

The source gate found three grow sites on store_ in the UDT graph unit
(resize_edges once, resize_payload twice) that the reviewed inventory did
not list. Add those three records; the inventory was emitted by the
scanner on this tree and compared with the committed file as a set of
records, and nothing else changes.

UdtGraph::node and UdtGraph::read_object called pine_na_stop, an inline helper
of the codegen contract, which put that symbol into libpineforge_kernel.a while
the kernel boundary keeps the helpers out of the archive. Raise the same coded
failure directly from a local function, as the array and matrix units do: the
same code (pine_na_reference), the same arguments and the same English text.
