 * JSON Source Map

 * This is used by the diagnostic formatter to produce LSP-compatible ranges
 * so FHIR validation issues highlight the exact source location of the
 * offending element in IDE integrations.
 *
 * The implementation is a small single-pass JSON tokeniser. It intentionally
 * avoids third-party dependencies and handles the subset of JSON the FHIR
 * validator is given (objects, arrays, strings, numbers, booleans, null).
