feat(spec,lint,metadata-protocol): a page member on the view type enum — mount a published page on an object view (#13372)

* feat(spec,lint,metadata-protocol): `page` member on the view type enum (#13216)

Adds a `page` member to `ListViewSchema.type` plus a `pageName` binding, so an
object list view / tab can mount an already-published custom page. Rendering is
delegated to the existing page renderer; no metadata type's authorization flags
are touched.

* test(lint): move the two shipped-form predicate census pins for the new `page` surface block

`view.form.ts`'s `page` section is gated by `visibleWhen: "data.type == 'page'"`
exactly as its seven sibling surface blocks are, so the shipped-metadata-form
corpus carries one more predicate (48 -> 49) and one more `==` literal
comparison (41 -> 42). Both pins track the corpus, not an issue; the expectation
moves in place with the reason recorded beside it.

Step 4 of scripts/pm/os-regen-merge.sh: the merge commit landed first (the
pre-commit hook recorded the deferral), and this commit is the regeneration on
top of it — schema, reference docs, liveness counts, api-surface and the
react-blocks contract, all from the merged tree.

+feat(spec,lint,metadata-protocol): a `page` member on the `view` type enum — mount an already-published page on an object view (#13216)
+
+A custom page created and published at runtime through the metadata API had no
+in-protocol way to reach an end user (#13100's evidence map). App navigation is
+closed to runtime content (`app.allowOrgOverride: false`), and the `view` `type`
+enum — on one of the five types the platform deliberately leaves open
+(`allowOrgOverride: true`, `allowRuntimeCreate: true`) — was closed over
+declarative row renderers, so a published page could not be mounted as an
+object's list view or tab.
+
+Maintainer ruling 2026-08-29 (live director session, verbatim 「同意」), 方向 1:
+
+> `view` 的 `type` 枚举新增 `page` 成员——对象的列表视图/标签页可挂载一个已发布页面。走平台**有意开着**的门(`view` 本就 `allowOrgOverride=true` + 运行时可创建),零新增授权面;设计要点:`page` 型 view 需声明 `pageName` 绑定,校验目标页面存在,渲染委托既有页面渲染器
+
+**Zero new authorization surface, as the ruling's basis requires.** Nothing in
+this change touches a metadata type's `allowOrgOverride` / `allowRuntimeCreate`
+flags, adds a write door, or adds a read door. A `page` view is a `view` written
+through the door `view` already opens, and it holds a NAME — the page itself is
+still fetched through the page read path it already had, and still renders
+through the existing page renderer, so the page's own audience gate
+(`page.assignedProfiles`) rides along unchanged. Delegation is what preserves
+that: a second renderer is what would have introduced a second gate.
+
+**The binding, refused in both directions at parse.** `ListViewSchema` gains
+`pageName`, declared with `SnakeCaseIdentifierSchema` — the same grammar
+`PageSchema.name` carries, so the accepted set is exactly the set of strings that
+could name a page. `checkListViewPageMount` then refuses:
+
+- `type: 'page'` with no `pageName` — unlike every other view type there is no
+  degraded rendering to fall back to, so the view would be blank;
+- `pageName` on any other view type — the accepted-and-ignored shape;
+- a non-empty `columns` beside a page mount — `columns` is the one required key
+  on a list view, and the only truthful value for a page mount is `[]`.
+
+The check is attached at all three list-view doors (`ListViewSchema`,
+`ObjectListViewSchema`, and the flattened runtime overlay behind
+`PUT /api/v1/meta/view`), with a pinned test that fails if any attachment is
+dropped.
+
+**Existence of the target page** is answered where the collection is visible:
+`defineStack`'s `validateCrossReferences` refuses at build time (same
+`pageNames.size > 0` policy the two other page references in that function
+already use), and the new `@objectstack/lint` rule `view-page-unresolved`
+(`validateViewPageRefs`) resolves it on `os validate` / `os lint` / `os compile`
+**and** at the runtime publish gate. Advisory, not gating, for its nav twin's
+reason: with no curated cross-package page registry, "unresolved here" cannot be
+told apart from "provided by a package this stack cannot see".
+
+Reaching the runtime publish gate needed the per-write snapshot to carry the
+`pages` collection (`RuntimeStackContext.pages`, threaded through
+`evaluateRuntimeAuthoringGate` and read off the live registry in
+`saveMetaItem`'s gate call). That is the one-key widening `RuntimeStackContext`
+documents, made when a rule that reads the collection crossed the wall — never
+in advance — and the false-positive channel it closes is measured both ways in
+`runtime-gate.view-page-refs.test.ts`. `pages` joined `NAME_KEYED_STACK_KEYS` in
+the same edit, because a collection that is both context-filled and
+write-targeted must have its finding paths name-keyed (#10064).
+
+**Downstream note (not an accept-set narrowing).** No previously valid metadata
+becomes invalid: `pageName` is a new key and `page` a new enum member, so every
+refusal above can only fire on a document that could not be written before.
+What does change for a downstream schema author is composition: `ListViewSchema`
+now carries a refinement, and zod 4 refuses `.omit()` / key-overwriting
+`.extend()` on a refined object. The unrefined shape stays module-private
+(publishing it would mint a duplicate protocol def and a second full set of
+ratcheted authorable-surface keys), so a consumer that derived from
+`ListViewSchema` by omission should compose with `.safeExtend()` or narrow after
+parsing. `FormViewSchema` has had this property since its own refinement landed,
+so this is the established shape for view schemas rather than a new one.
+
+**Deliberately out of scope**, per the same ruling: 方向 2 (registering app
+navigation at publish time) is deferred to its own design card — it would
+require reversing the `app.allowOrgOverride: false` authorization decision — and
+with it the known limitation the ruling accepts on the record, that a page
+belonging to no object still has no browse-to entry. `page` is also NOT added to
+`VisualizationTypeSchema`: the switcher offers alternative ways to draw the same
+rows, and a page draws none.
