 * Handles the JSON Schema `if`/`then`/`else` conditional keywords.
 *
 * Per JSON Schema draft 2020-12: when the instance validates against the
 * `if` subschema, it must also validate against `then` (when present);
 * otherwise it must validate against `else` (when present). A lone `if`
 * (without `then` and `else`), or `then`/`else` without `if`, imposes no
 * constraints. Boolean subschemas (`if: false`, etc.) are honored.
