/**
 * Fix Patch Applier (D-1 phase 1)
 *
 * Takes a resolved `FixPatch` (one that has already been run through
 * `resolvePatch()` so the `{{key}}` templates are expanded) and applies
 * it to a deep-cloned copy of a FHIR resource.
 *
 * Supported path syntax:
 *   - dot paths:           `Patient.gender`
 *   - array indexing:      `Patient.identifier[0].system`
 *   - resource-type prefix optional: `Patient.gender` and `gender` both work
 *
 * Not supported (intentionally — these need full FHIRPath, which is
 * what the validator engine itself uses):
 *   - choice-type collapsing (`Observation.value` instead of
 *     `valueQuantity`)
 *   - filters (`Patient.identifier.where(use='official').system`)
 *   - traversal across references
 *
 * The applier is a *patch executor*, not a fixer that infers the right
 * value. Callers are expected to supply a concrete `value` in the patch.
 * Patches whose `value` still contains `{{...}}` placeholders are
 * rejected (they came out of `resolvePatch()` unresolved).
