Jinwoo Hong 6013d093e2 fix(mobile): one host sidebar on iPad, with the page owning the host area (#26761)
* feat(mobile): let the page own the wide host area, one sidebar only

On wide layouts a detail route's page session ran app/h/_layout.tsx inside
the detail pane, judged itself wide, and drew a second host sidebar beside
the native one.

- The page draws the host sidebar only when init carries the new optional
  `ownsHostArea` fact, never from its own width.
- The page manifest's `/h/[hostId]` route declares `canOwnHostArea`.
- On wide layouts the native host route mounts one host-area page session.
  A declaring bundle serves it with every served route's grants, so hops
  stay in the page, and the native layout drops its sidebar. Without the
  declaration, or without a bundle, the session answers native-route and
  every wide detail route stays native.
- The owner is recorded per host so the layout and switches agree and a
  relaunch does not flash.

* fix(mobile): decide the wide host area per session, without a stored owner

Round 1 kept a per-host owner record that the native layout trusted. When
the record said the page owned the area, a detail route opened natively
(deep link, notification, handoff, narrow-to-wide with a detail pushed)
showed no sidebar at all.

- Drop the record. A wide session decides from the manifest it already
  read: it is served only when the host route declares canOwnHostArea,
  and it rebuilds when the layout class changes.
- The native layout hides its sidebar only on the host route, while that
  host's page session is serving, as the shell screen reports through a
  layout context. Detail routes keep the native sidebar, and a page there
  draws none, so there is exactly one.
- Phones read and render nothing new.
- The host-area page can read and write every workspace-scoped key of its
  host (chat tabs, live-input handles), as a per-workspace session does.

* test(mobile): type the layout-class doubles rather than assert them

* fix(mobile): keep detail pages through a layout flip, guard capped keys

- A wide/narrow flip rebuilds a session only on the host route or under a
  bundle without canOwnHostArea, where the answer changes. A detail page
  under a declaring bundle keeps its document, scroll and draft.
- In the host-area page, a workspace key the 32-entry init cap leaves out
  is named in storageOversize, so the page cannot replace the device's
  chat-tab list from a default. The init frame bounds that list to the
  page's schema; the host still refuses every key in the full list.
- A leaving host-area session clears only its own report.

* refactor(mobile): host-area ownership from the reducer, storage read on demand

- The serving report is a focus-scoped boolean, so a host pushed over
  another no longer leaves the first one's area unclaimed after the pop.
- The reducer takes `layout-changed {wide}`: it keeps the session when the
  route view is unchanged and restarts it otherwise; `routeViewOf` returns
  `ownsHostArea`.
- One web override, `usePageOwnsHostArea`; the native rule is inline in the
  host layout.
- A host-area page reads a host workspace key from the shell on demand
  (`native.storage.read`, granted to that session only) instead of init
  enumerating the store.

* fix(mobile): host-area page reads back its own workspace-key writes

A page read right after a page write of the same key is answered from the
page's own value, not from a shell that may not have the notify yet. A
refused read crosses as an error, never as an unset key.

* refactor(mobile): read-your-writes from the shell's mirror, final review fixes

- The shell answers a workspace-key read from the mirror, which every
  shell-side write updates synchronously (removals held as known-absent),
  and reads the store only on a miss. The page shim's written-keys set
  goes.
- `onLayoutChanged` compares the route view field by field; the session
  is created with its layout and the layout effect fires on `wide` alone.
- The device verb dispatcher's type excludes the storage read.
- The sidebar matrix mounts the real shell screen to decide the report.

* feat(mobile): host-area page takes the whole screen from the download on

The native sidebar steps aside once the manifest says the page owns the
host area: fetching, activating, ready and the failure screens after them
are full screen, as on a phone. It stays while the host is being checked.

* fix(mobile): host-area workspace-key read survives a write during it

On a mirror miss the read went through the mirror's hydrate, which drops
its answer when any mirrored write lands meanwhile, so a stored key read
as unset right after a relaunch. A miss now reads the store directly, and
a store failure rejects rather than reading as unset.

* fix(mobile): a wide detail session hands the host route to the shell

A session opened on its own under a page that can own the host area
kept a hop to the host route in-page (a missing worktree's notice, or
leaving the session), drawing a second host list beside the native
sidebar. Its pairs now leave the host route out, so the hop goes to the
shell, which opens the area-owning session. Phones keep the hop in-page.

* test(mobile): a phone mount's layout dispatch leaves the session alone

* fix(mobile): leaving a wide detail session returns to the host area

The leave-session chevron and the missing-worktree bounce hand the host
route to the shell on a wide layout, which pushed it: a second host-area
session over the session, with Back reopening the session. On a wide
layout the shell now dismisses to this host's route instead, taking the
href's params, or replaces the session when nothing is below it. Phones
still push.

* fix(mobile): a narrow-wide flip restarts a detail session's page

The route view comparison now counts the paired routes, so a detail
session under a page that can own the host area restarts on a flip
instead of keeping the narrow pairs, whose host-route pair let the page
draw a second host list beside the native sidebar.
