Data structures not representable in output format should result in an error.

[clonezone]

Describe the bug

YAML can represent data structures that other formats supported by yq cannot, for example, graphs of objects that have cycles in them.

Here's a YAML representation of an array containing a single element: itself.

---
&1
- *1

If I ask yq to give me the JSON representation, it gives incorrect output.

> yq --output-format json . self-referential.yaml
[
  [
    []
  ]
]

The problem is that the input is not properly representable in JSON. This should produce an error.

Version of yq: 4.44.3 Operating system: macOS 14.7 Installed via: homebrew

Input YAML

data1.yml:

---
&1
- *1

Command

yq --output-format json . data1.yml

Actual behavior

[
  [
    []
  ]
]

with an exit code of 0.

Expected behavior

Error with a non-0 exit code.

Additional context

None.
