taurus v0.11.4

Fixes

• #253: taurus_doctype_get_internal_subset now returns the raw
  DTD internal subset text. Previously direct_parse extracted the
  subset for entity parsing but didn't store it on the DOCTYPE node.

• #217: taurus_element_append_child correctly unlinks a child
  before re-appending, even when the parent is the same element
  (re-ordering). The old old_parent != elem check skipped
  unlinking for same-parent moves, causing duplicate children and
  inflated child_count.

New API

• #262: taurus_xpath_result_get_nodes(result, out, max) —
  batch-copy all nodes from a nodeset result in one call. Eliminates
  per-node FFI overhead for bindings iterating large nodesets
  (100+ nodes).
