## **Description**

**Goal:** Close **INFRA-3628 Phase 5b** — make Namespace-hosted CI jobs
use Namespace’s supported checkout path instead of treating them like
GitHub-hosted runners, without changing how **`runner_provider:
current`** behaves today.

**What we shipped:** Every place the workflow graph already chooses
Namespace via `runner_provider` now checks out with **nscloud checkout
on `namespace`** and keeps the **existing `actions/checkout` path on
`current`** (same majors / `if:` guards so the default path stays
equivalent). That covers the main **`ci`** graph, reusable builds and
node-modules setup, iOS/Android E2E build workflows, the callable
**`run-e2e-workflow`** runner, and the **smoke/regression report** jobs
that also land on Namespace Linux when trialing Namespace.

**E2E setup:** The shared **`setup-e2e-env`** composite accepts optional
**yarn** and **CocoaPods** per-attempt retry timeouts;
**`run-e2e-workflow`** raises the outer **`Set up E2E environment`** cap
for **Namespace + iOS** and passes those inputs so parallel iOS smoke is
less likely to die mid-install under contention. This is a stability
cushion; deeper Namespace CocoaPods cache work can follow the same
ticket / INFRA-3596 thread.

**Scope note:** No app or product behaviour changes — CI and composite
action YAML only.

## **Manual testing steps**

```gherkin
Feature: INFRA-3628 Namespace checkout pilot

  Scenario: Current runner path is unchanged
    Given ci (or downstream workflows) run with runner_provider current
    When checkout steps execute
    Then the same actions/checkout path runs as before and nscloud checkout is skipped

  Scenario: Namespace runner path uses nscloud checkout
    Given the same workflows run with runner_provider namespace
    When checkout steps execute
    Then nscloud checkout runs on Namespace profiles and actions/checkout is skipped

  Scenario: Namespace iOS E2E smoke can finish environment setup more often
    Given a Namespace dispatch with a full iOS smoke matrix
    When each shard runs Set up E2E environment
    Then setup is less likely to hit the previous hard timeout during CocoaPods under parallel load
```

## **Screenshots/Recordings**

N/A — infrastructure / CI only.

- [x] I've followed [MetaMask Contributor
Docs](https://github.com/MetaMask/contributor-docs) and [MetaMask Mobile
Coding
Standards](https://github.com/MetaMask/metamask-mobile/blob/main/.github/guidelines/CODING_GUIDELINES.md).
- [x] I've completed the PR template to the best of my ability
- [x] I've included tests if applicable (validated via `pull_request` CI
and Namespace `workflow_dispatch` trials on this branch)
- [x] I've documented my code using [JSDoc](https://jsdoc.app/) format
if applicable (N/A — YAML / workflow config only)
- [x] I've applied the right labels on the PR (see [labeling
guidelines](https://github.com/MetaMask/metamask-mobile/blob/main/.github/guidelines/LABELING_GUIDELINES.md)).
Not required for external contributors.

#### Performance checks (if applicable)

N/A — no app or bundle changes.

- [ ] I've tested on Android
  - Ideally on a mid-range device; emulator is acceptable
- [ ] I've tested with a power user scenario
- Use these [power-user
SRPs](https://consensyssoftware.atlassian.net/wiki/spaces/TL1/pages/edit-v2/401401446401?draftShareId=9d77e1e1-4bdc-4be1-9ebb-ccd916988d93)
to import wallets with many accounts and tokens
- [ ] I've instrumented key operations with Sentry traces for production
performance metrics
- See [`trace()`](/app/util/trace.ts) for usage and
[`addToken`](/app/components/Views/AddAsset/components/AddCustomToken/AddCustomToken.tsx#L274)
for an example

For performance guidelines and tooling, see the [Performance
Guide](https://consensyssoftware.atlassian.net/wiki/spaces/TL1/pages/400085549067/Performance+Guide+for+Engineers).

## **Pre-merge reviewer checklist**

- [ ] I've manually tested the PR (e.g. pull and build branch, run the
app, test code being changed).
- [ ] I confirm that this PR addresses all acceptance criteria described
in the ticket it closes and includes the necessary testing evidence such
as recordings and or screenshots.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Touches a broad set of CI workflows and checkout paths; while behavior
is intended to be equivalent for `runner_provider: current`,
misconfigured `if:` guards or checkout options could break builds/tests
specifically on Namespace runners.
> 
> **Overview**
> Updates the CI workflow graph (main `ci.yml`, reusable build
workflows, E2E smoke/regression runners, and `setup-node-modules`) to
**conditionally use `namespacelabs/nscloud-checkout-action` when
`runner_provider == 'namespace'`**, while keeping the existing
`actions/checkout` path for `current`.
> 
> Extends the `setup-e2e-env` composite action with new inputs for
**per-attempt retry timeouts** (JS deps/Corepack and CocoaPods), and
updates `run-e2e-workflow.yml` to increase the overall setup timeout for
**Namespace+iOS** and pass larger timeout values into the composite.
