fix: align sveltekit adapter tests with dispatch() catch-all pattern

[Copilot]

SvelteKit adapter was refactored to use the unified dispatcher.dispatch() catch-all (like all other adapters), but tests still mocked the old handleMetadata/handleData methods — causing 7/19 tests to fail with 500s.

• Replaced handleMetadata/handleData in mock with dispatch
• Updated assertions for metadata, data, error handling, and toResponse tests to match the catch-all contract

// Before (stale mock — dispatch() undefined → throws → 500)
const mockDispatcher = {
  handleMetadata: vi.fn().mockResolvedValue({ ... }),
  handleData: vi.fn().mockResolvedValue({ ... }),
};

// After (matches implementation)
const mockDispatcher = {
  dispatch: vi.fn().mockResolvedValue({ handled: true, response: { body: { success: true }, status: 200 } }),
};

Aligned with the hono adapter test conventions, which already use this pattern.

Pull request overview

Updates the SvelteKit adapter test suite to match the adapter’s current unified routing approach, where non-auth/graphql/storage/discovery routes are handled via HttpDispatcher.dispatch() (consistent with other adapters).

Changes:

• Updated the SvelteKit adapter test mock to implement dispatch() (removing obsolete handleMetadata/handleData mocks).
• Adjusted Metadata/Data/Error handling/toResponse tests to assert the dispatch(method, path, body, query, context) catch-all contract.
• Documented the fix in CHANGELOG.md.
