redux-saga-testing

@anivar

Write tests for Redux Sagas using redux-saga-test-plan, runSaga, and manual generator testing. Covers expectSaga (integration), testSaga (unit), providers, partial matchers, reducer integration, error simulation, and cancellation testing. Works with Jest and Vitest. Triggers on: test files for sagas, redux-saga-test-plan imports, mentions of "test saga", "saga test", "expectSaga", "testSaga", or "redux-saga-test-plan".
