Why

Fixes #4205.

EAS CLI currently bundles an older Expo config-loading stack that can fail to read valid TypeScript app.config.ts files in two cases:

• configs that use import.meta can fail when the bundled fallback is evaluated as CommonJS
• TypeScript 7 exposes no compiler API through the typescript package stub, so the older require-utils path dereferences a missing ModuleKind.CommonJS

The SDK 56 config stack already contains the fixes for both cases.

How

• update the bundled Expo config stack to the SDK 56 line:
  • @expo/config@56.0.14
  • @expo/config-plugins@56.0.16
  • @expo/prebuild-config@56.0.23
  • this resolves @expo/require-utils@56.1.7
• preserve the legacy splash validation read after the SDK 56 config type change
• narrow update workflow typing to the platforms EAS Update actually publishes
• adapt the exempt-encryption memfs test mock to SDK 56's resolveFrom-based config path resolution
• regenerate yarn.lock

Test Plan

The original validation run on the pre-refresh branch passed the TypeScript 7 and import.meta reproductions, workspace build, fallback and exempt-encryption tests, typecheck, formatting, lint, and all 325 Jest suites: https://github.com/erenbati/eas-cli/actions/runs/34762593768

After merging current upstream main at f949f34 (head 6675cdd):

• corepack yarn workspace eas-cli typecheck-for-build passed
• bundled-config fallback tests passed (3/3)
• the update command and exempt-encryption test suites passed
• the full Jest suite on Windows passed 329/363 suites; remaining failures include POSIX path and locale assumptions, and the publish/PNG validation tests need Linux CI confirmation
• the root workspace build reaches copy-new-templates but its mkdir -p command is not supported by the Windows shell
• the latest PR Actions runs are waiting for maintainer approval (action_required); they have not run on this head

Checklist

• I've added an entry to CHANGELOG.md if necessary.
