## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/processes/updating-changelogs.md)
  * Not applicable, test only change. Carries the `no-changelog` label.
- [ ] I've introduced [breaking
changes](https://github.com/MetaMask/core/tree/main/docs/processes/breaking-changes.md)
in this PR and have prepared draft pull requests for clients and

  * None.

<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Low Risk**
> Test-only and tooling changes; production controller code is
unchanged.
> 
> **Overview**
> **Migrates `@metamask/delegation-controller` and
`@metamask/gator-permissions-controller` from Jest to Vitest**,
following the same package-level pattern used elsewhere in the repo
(shared `vitest.config.packages.js`, per-package `vitest.config.ts` with
prior coverage thresholds).
> 
> For each package, **test scripts and devDependencies** switch to
Vitest; **Jest config and `jest` TypeScript types** are removed. Test
sources are updated mechanically (`jest` → `vi`, Vitest imports,
`vi.mock` with dynamic import in gator-permissions, `flushPromises` from
`tests/vitest/helpers.js`).
> 
> **Repo wiring:** both packages are dropped from the Jest runner map in
`test-runner-package-map.cjs`, and `oxlint-suppressions.json` is
adjusted (including `vitest/no-conditional-in-test` entries for
gator-permissions tests).
