The JSON parser's value/object/array readers are mutually recursive with
no depth limit, so input nested tens of thousands of levels deep overflows
the stack with an uncatchable StackOverflowException (CWE-674) that kills
the process. This is reachable through DotNetCorePathFinder, which parses
the .deps.json shipped next to an opened assembly, so a crafted manifest
beside a target turns dependency resolution into a clean process kill.
Thread a depth counter through the readers and throw a catchable
JsonParseException once nesting passes a fixed cap. The cap (64) matches
the System.Text.Json default and is far beyond any real dependency graph.
