Refuse a stale PDF form whole-value write
pdf-set-form-value now requires expectedValue. A drifted base fails closed and writes nothing, so a stale whole-field write cannot overwrite a concurrent edit.
- Compare and swapexpectedValue must equal the current field value, or be empty when the field is absent.
- Fail closedA mismatch returns mutation_match_conflict and leaves the replica unchanged.
- Span editsPass the find hit search and indexUtf16 to change only that span of the field value.
