filterCirculars

Creates a clean, JSON safe copy of a value and replaces circular references with a marker.

In jsonjson mode it behaves like stringify then parse with a replacer that handles cycles and BigInt. In decycledecycle mode it first clones without using toJSON, then you can stringify the result later.
