Function load_unified_graph 

pub fn load_unified_graph(
    root: &Path,
    config: &GraphLoadConfig,
) -> Result<CodeGraph>

Load a unified code graph using the new Arena+CSR storage architecture.

This is the preferred entry point for CLI graph operations. It loads a graph either from a persisted snapshot or by building from source files.

Loading Strategy

1. First tries to load from persisted snapshot (.sqry/graph/snapshot.sqry)
2. If no snapshot exists, builds from source files using language plugins

Arguments

• root - Root directory to scan for source files
• config - Configuration for file walking (hidden files, symlinks, depth)

Returns

A CodeGraph populated with nodes and edges from all supported languages

Errors

Returns an error if the path is missing, the snapshot is invalid, or the graph build fails.

Example

use std::path::Path;
use sqry_cli::commands::graph::loader::{load_unified_graph, GraphLoadConfig};

let config = GraphLoadConfig::default();
let graph = load_unified_graph(Path::new("."), &config)?;
