Change kill-switch from maxDepth = -1 to maxDepth = 0 (equivalent behavior, clearer intent). Add test suite visualizing the budget behavior: early elements expanded, later elements folded. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This is a breaking change imho as it breaks existing snapshots that are above 1MB, should have been labeled as such. |

Broke some of our tests as well. I could see how this is a bug fix, but I don't understand how we can set this limit, is it not possible or just undocumented? |

Description
Several approaches is mentioned in the note above. This PR took the simplest approach inspired by Node's
util.inspect. See 2nd approach in the note.This doesn't necessarily supersede #9920 since that's more about heuristics of improving the error diff for obvious case. This PR is only about implementing the guard for worst case.
