Isolate provider debug in tests/providers/kiro/kiro-stream.test.ts:41-60.

The shared setup clears only OCX_DEBUG_FRAMES. It does not clear OCX_DEBUG or reset the runtime override used by isDebugEnabled(). An enabled setting can enter the diagnostic branch in src/adapters/kiro.ts:2125, call TextEncoder.encode(body), and fail this assertion. Reset the runtime debug settings and disable the provider debug environment variables in beforeEach; restore both in afterEach.

In `@tests/providers/kiro/kiro-stream.test.ts` around lines 199 - 200, Update the
shared test setup around the beforeEach/afterEach hooks to reset the runtime
override used by isDebugEnabled(), clear provider debug environment variables
including OCX_DEBUG, and explicitly disable provider debug before each test.
Restore the prior runtime setting and environment values after each test so
diagnostic behavior cannot leak between tests.
