/**
 * Resolve the evaluation context and (possibly rewritten) expression for a constraint.
 *
 * Two cases require special handling:
 *
 * 1. **Choice-type elements (`[x]`)**: fhirpath.js loses type metadata when
 *    values are extracted as raw JS primitives, so `$this as dateTime` etc.
 *    fail. Fix: keep the parent as context and wrap the expression with
 *    element navigation (`effective.all(...)`) so FHIRPath resolves the
 *    typed value through the model.
 *
 * 2. **Backbone elements** (component, contact, etc.): extracting a backbone
 *    element as a raw JS object strips `resourceType`, so fhirpath.js can't
 *    resolve choice-type children (e.g. `value.exists()` fails because
 *    `valueQuantity` isn't found via the FHIR model). Fix: evaluate from
 *    the resource root and navigate with `pathSegments.all(expr)`.
