joi has an uncaught RangeError on deeply nested input through recursive `link()` schemas

### Impact Denial of service via untrapped exception in services validating user-supplied JSON / object input with recursive link schemas. The blast radius depends on how the application invokes joi: - Highest impact: `validate()` called without `try/catch` in a request handler would cause an unhandled exception, potentially crashing the process. - Lower impact: `validateAsync()` or `validate()` inside a `try/catch`, the validation fails, but the error type is `RangeError` rather than a structured `ValidationError`, complicating error handling. ### Patches Upgrade to version >= 18.2.1. ### Workarounds Try/catch the validation to avoid uncaught exceptions. ### References - Pull request: hapijs/joi#3113
