fix(app): retain checkout selection after workspace failure

Return the submitted checkout through the existing draft failure handoff. Keep client-owned receipt ordering and retries out of app presentation, and retain direct coverage of newer draft cleanup while removing the unused background-agent wrapper.

-identities, not ready workspace records.
+The New workspace chat entry requires `creationLifecycle`; empty workspaces, terminal
 launches, and existing-workspace agent drafts retain their own entry points.
 Pending presentation never enters the directory replica as a fabricated resource.
 Routes, tabs, and the sidebar retain it until the corresponding authoritative resource
 has been observed. Files, terminals, scripts, and agent timeline initialization wait for
 real resources. The creating agent opens in the normal agent panel and composer, showing
 its submitted configuration. Until the host publishes the agent, its destination cwd is
 unknown and its controls are read-only. The host publishes the agent before it starts the
 initial prompt, so prompts wait in the agent's queue until creation completes
 (`isAgentReadyForPrompts`). `composer/actions.ts` applies that to every prompt path: send
 and review feedback queue behind earlier prompts, and send now and queue drain leave the
 queue untouched. The queue drains on adoption or when the initial turn ends. The first
 message uses composer submission reconciliation; creation never sends it again when the
 panel mounts. Completion does not navigate, and draft cleanup checks the captured version
 so it cannot erase newer input.
 A failed creation goes to the existing owner of whatever the host did not create, using
 the receipt's resources and `failedStage`. Creation has no failure UI of its own:
 - No workspace: the app returns to New workspace with the submitted draft and checkout
  selection, and shows the error the way that screen shows its own submit errors.
 - Workspace but no agent: the agent tab becomes an existing-workspace agent draft holding
  the prompt, in the abandoned create-flow state. Its error and Send retry are that draft's
  own; the retry creates the agent in the kept workspace.
 - An agent that exists or may exist, including a failed first prompt: creation completes
  and the agent tab keeps the agent's own timeline and turn error. Turning it into a draft
  would create a second agent on Send.
 Queued follow-ups and unsent composer text belong to a composer identity, so they move
 with the creation: from the form to the creating agent, back to the form or the agent draft
 on failure, and to the created agent after retry (`transferComposerFollowUps`). The initial
 prompt stays the form's or draft's input. The agent draft also carries the submitted
 setup and context attachments. The host ignores `config.cwd` when a create request names a
 workspace, so a draft's retry starts at the workspace root, not a nested fork cwd.
 Adopted successful attempts release their payloads; a bounded cache of compact receipts
 absorbs duplicate commands from retained forms. The SDK owns reconnect observation; the
 app has no resend loop. Pending views survive navigation and pane remount, not app
 process death. Resource reservations are identities, not ready workspace records.
 The creation journal (`server/creation/`) owns identity and execution for both legacy and
 modern creation RPCs. Requesting progress never selects a different journal. Existing

 ## Dependency overrides and workspace tooling
 Root `package.json` `overrides` pin one Expo SDK across the tree (`expo`, `expo-router`,
 `react-native`, …). npm does not apply those overrides to packages it places under a
 workspace's own `node_modules`. When `expo-module-scripts` was declared in
 `packages/expo-two-way-audio`, npm nested it there and its `jest-expo` peer `expo@*` resolved to
 a second, newer Expo SDK and React Native: 200+ duplicate packages nothing imported (#7730).
 Declare tooling that peer-depends on `expo` or `react-native` in the root `devDependencies`,
 where the overrides apply; workspace scripts still find the binary through the root
 `node_modules/.bin`.
 ## Dependency signature audit
 The `quality` CI job runs `npm audit signatures`. It verifies every lockfile package's registry
 signature and, for packages published with provenance, fetches
 `/-/npm/v1/attestations/<name>@<version>` from the registry. Cloudflare caches that document
 for a year. An edge that cached it in the seconds before the registry attached the publish
 attestation keeps serving a document with only the provenance bundle, and npm fails with:
 ```
 npm error code EMISSINGSIGNATUREKEY
 npm error <name>@<version> has attestations but no corresponding public key(s) can be found
 ```
 The same package's registry signature verified a moment earlier with the same keys, so the
 key list is intact. The failure names one package, repeats only for that package, and depends
 on the Azure region the runner landed in, because each region maps to one Cloudflare colo. A
 rerun passes only by landing elsewhere.
 To confirm, fetch the URL from several runners and compare `content-length`, the `cf-ray` colo
 suffix, and the number of `attestations` entries (#7730 has the probe). To fix, remove or
 replace that version in the lockfile and report the URL to npm so they purge it.

+Opening or resuming an agent fetches one bounded latest tail page. Older history remains
 projected items. Backward pages and prompt-jump windows also include whole turns, including
 all currently available rows of an active run. There is no per-turn cap: a large run can
 exceed the target. Local history mounting uses the same boundaries so revealing older rows
 does not change the collapse state of a turn already displayed.
 `wholeTurns` is a preference negotiated once at the client fetch boundary. Hosts advertising
 `features.wholeTurnTimeline` receive it; other hosts receive the existing item-based request.
 Reading history remains available on older hosts, whose pages can still split turns. Forward
 catch-up stays incremental, but its reset snapshot honors a supported whole-turn request.
 Source coverage still includes interleaved tool updates.
 Canonical IDs define runs. With missing IDs, human prompts, heartbeats and typed received
 agent messages each start a fallback turn. This deterministic fallback is shared by paging
 and presentation; it cannot recover historical batching or steering. Older history remains
 user-driven by scrolling upward.
 A failed catch-up or subscription reconcile retries on its own, doubling from 1s to a 30s ceiling.
