Jinwoo-H dc6d577096 fix(mobile): stop a page mount that lost its claim before it writes the scope
Round 5 on #21809.

F1 (blocking). `buildTerminalWebDocument` had no token, so after its `await
import(...)` the whole body ran whatever had happened in the meantime: it
overwrote the six seams, called `startPageDocumentModules` and added the resize
listener, and only then did the caller's `.then` read the claim and throw the
result away. Everything after that await is shared — the seams are fields on a
module-singleton scope, and the start sequence resets that scope and installs
the document's listeners — so a mount disposed while its chunk was in flight was
writing over a mount that owns the page. The claim is now re-read the instant
the import lands, before any of it, and the build returns null.

`ready` for such a mount resolves rather than rejecting. Nothing failed: the
caller asked for the terminal and then asked for it to go away, and the chunk
arriving afterwards is not something for the error overlay to name. Before this
it rejected with a TypeError from `startSelectionMenuButtons` reaching for an
emptied host.

F2. The rejection handler called `release()` unconditionally, emptying a host the
mount may no longer own. It now releases only when the page is still its own.

Pins, both red first. In happy-dom: mount, dispose, then await ready — no
listener, timer or frame added while it resolves, the six seams unchanged,
`terminalGeneration` unmoved because the start sequence never ran, and the page
free for the next mount. Without the fix that case rejects with the
`startSelectionMenuButtons` TypeError. In the browser, the Reload-while-in-flight
case now reads the page's listeners with no terminal on it and compares them
against a page that mounted once and disposed once; without the fix the
abandoned mount leaves `window error` and `window resize` behind, because the
second mount's scope reset nulls the first mount's reporter undo.

The listener snapshot helper is shared with the mount-and-dispose case rather
than written twice.
