Module content_dispatch 

Content trait dispatch — render any ValueWord value as a ContentNode.

The render_as_content function implements the Content trait dispatch logic:

1. If the value IS already a ContentNode → return as-is
2. Match by NanTag/HeapValue type → built-in Content impls for primitives
3. Fallback → Display as ContentNode::plain(display_string)

Built-in Content implementations:

• string → ContentNode::plain(self)
• number/int/decimal → ContentNode::plain(formatted)
• bool → ContentNode::plain(“true”/“false”)
• Vec → ContentNode::Table with columns from schema fields
• Vec → ContentNode::plain(“[1, 2, 3]”)
• HashMap<K,V> → ContentNode::KeyValue
• TypedObject → ContentNode::KeyValue with field names from schema

ContentFor

The render_as_content_for function adds adapter-aware dispatch:

1. ContentFor → adapter-specific rendering
2. Content → generic content rendering
3. Display fallback → plain text

Adapter types: Terminal, Html, Markdown, Json, Plain
