Test the local test selection too.

This assertion checks the CI output, but it does not exercise check:changed test selection. Removing the new selection branch would leave this test passing. Add a focused test that verifies a guide change selects ConnectReachability.test.ts.

As per path instructions, “Test behavior that can break, including logic changed by a bug fix.”

Review comment at @scripts/check-changed.test.ts around lines 39 - 40:
Add a focused assertion in the tests for decide that a change to
docs/user/t3-connect-troubleshooting.md selects ConnectReachability.test.ts in
the local check:changed test-selection output, rather than only verifying the CI
output. Ensure the test would fail if the guide-specific selection branch were
removed.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
