Module builder 

Builder pattern implementations GraphRAG builder module

This module provides builder patterns for constructing GraphRAG instances.

Two Builder Options

1. Simple Builder (GraphRAGBuilder) - Flexible, runtime validation

use graphrag_core::builder::GraphRAGBuilder;

let graphrag = GraphRAGBuilder::new()
    .with_output_dir("./my_output")
    .with_chunk_size(512)
    .build()?;

2. Typed Builder (TypedBuilder) - Compile-time validation

use graphrag_core::builder::TypedBuilder;

// This won't compile until you configure required settings!
let graphrag = TypedBuilder::new()
    .with_output_dir("./my_output")  // Required - transitions state
    .with_ollama()                    // Required - transitions state
    .with_chunk_size(512)             // Optional
    .build()?;                        // Only available when properly configured
