Overview

Walks a CoreModel tree and resolves InlineElement nodes whose format_type is 'attribute_reference' against a Metadata store.

AsciiDoc {foo} references round-trip as InlineElement with format_type: 'attribute_reference' and target: 'foo'. After the document is parsed and its attributes are known, this visitor rewrites those nodes in place to TextContent carrying the value. Unresolved references are left untouched so they survive serialisation back to the source format.

The visitor never mutates its input tree; it returns a new tree sharing unchanged subtrees. InlineElement#with_content already produces non-mutating copies for inline content; the same pattern is used here at the block level via replace_children.
