docs(changeset): name the container stored under one of its own expanded names

A view item saved under an expanded name is what the object door now
lists; a container stored under such a name is its own row too, so the
object door (which never lists a container) lists nothing there.

-- **What changed.** `GET /api/v1/meta/view?object=…` (the object door) no longer lets a stored view container's expansion replace a stored row of the same name. A row saved under a name the container also expands, such as `<object>.default` beside a stored overlay of that object's container, is now what the object door lists under that name. Before, the object door listed the container's expansion there while the by-name read (`GET /api/v1/meta/view/NAME`) answered the stored row. Both doors now answer the row.

 - **The rule.** A row stored under exactly a name is the override for that name (ADR-0005 keys an overlay by its own name). An expansion fills only the names that have no row of their own. The list read and the by-name read decide this with one test, over the rows each selects for the same caller, so a row stored for one organization does not hide the expansion from any other caller.
-- **What does not change.** Every other name a container expands is still listed, and on both doors it still replaces a packaged view of the same name. The by-name read answers as before. The save door is unchanged. No response shape gains or loses a key.
