Explanation

Stacked on #10873. Remove ignoreSourceErrors from network-controller's Vitest configuration so source diagnostics also fail the test command.

Use a non-composite test tsconfig without project references and explicitly select the declared @typescript/native compiler. skipLibCheck follows the repository's existing build/lint policy for dependency declarations.

Remove obsolete clock arguments, move an expected-error directive to the invalid property, and give the mixed client registry its existing union type in the test. Remove the 21 TSC suppressions these fixes make unnecessary.

Validation

• All 5,338 package tests pass, including the type test; coverage thresholds pass.
• A broken type assertion fails the default test command while all 5,337 runtime tests pass.
• An unused @ts-expect-error and a source-only type error each fail type checking. All temporary mutations were restored.
• Root TSC, lint, formatting, tsconfig checks, constraints, dependency checks, CODEOWNERS, and changelog validation pass.
• Type checking also passes on Node 22.14; yarn install --immutable passes.

References

• Depends on test: run network-controller on Vitest #10873.

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation as appropriate: no consumer documentation changes needed
• I've communicated changes to consumers with changelogs: not applicable, test-only changes
• I've introduced breaking changes: none

Note

Low Risk
Changes are limited to test tooling configuration and test-only type fixes; no production runtime behavior is modified.

Overview
Enforces real TypeScript checking on network-controller tests instead of ignoring source errors during Vitest typecheck.

Vitest now runs the native @typescript/native checker against a new tsconfig.test.json (non-composite, noEmit, skipLibCheck, no project references). Related entries are removed from tsc-suppressions.json.

Test fixes so the suite typechecks cleanly: explicit typing for getNetworkClientRegistry() in NetworkController.test.ts, repositioned @ts-expect-error on the intentional bad RPC payload in rpc-service.test.ts, and dropped obsolete clock arguments to waitForPromiseToBeFulfilledAfterRunningAllTimers in shared network-client test helpers.
