Add Options::emit_anchor_events (default false) to emit Event::Anchor(id, name)
immediately after the anchored scalar or collection-start event. Its span covers the complete
&name token, and its ID matches the node and resolved aliases without relying on allocation
order. Anchor events are presentation metadata (is_node() is false); existing node payloads
and default event streams are unchanged. Together with alias-token spans and Span::tag_span(),
this exposes original property spellings without separate anchor and tag scans.
