Module reader 

XML Reader API (§30, §85 Phase 7).

Cursor-based streaming reader with node type, depth, attribute traversal, namespace lookup, value retrieval, validation integration.

Implements the xmlTextReader API from libxml2, which provides a cursor-based streaming interface for reading XML documents. The reader parses the entire document into a tree on the first Read() call, then walks the tree in document order (depth-first traversal) generating node events for elements, text, comments, PIs, etc.

UPSTREAM-PARITY

The reader API is defined in libxml/xmlreader.h and libxml/xmlreader.c. Key differences from upstream:

• The reader parses the full document on first Read rather than using a true streaming/event-driven parser. This simplifies the implementation while preserving the observable API surface.
• Pattern-based reader operations (xmlTextReaderPreservePattern, etc.) are not yet implemented.
