Struct TextModifierNode 

pub struct TextModifierNode { /* private fields */ }

Node that stores text content and handles measurement, drawing, and semantics.

This node implements three capabilities:

• Layout: Measures text and returns appropriate size
• Draw: Renders the text (placeholder for now)
• Semantics: Provides text content for accessibility

Matches Jetpack Compose: TextStringSimpleNode in compose/foundation/foundation/src/commonMain/kotlin/androidx/compose/foundation/text/modifiers/TextStringSimpleNode.kt
