#![cfg_attr(coverage_nightly, coverage(off))]
//! Project analyzer for codebase exploration and dependency analysis
//!
//! This module provides the core project analysis functionality, serving as
//! the entry point for analyzing codebases. It coordinates file discovery,
//! source file identification, and dependency graph construction to provide
//! a comprehensive view of project structure.
//!
//! # Features
//!
//! - **Automatic File Discovery**: Finds all relevant source files in a project
//! - **Language Detection**: Identifies programming languages by file extension
//! - **Dependency Graph Building**: Constructs relationships between code elements
//! - **Gitignore Respect**: Automatically excludes ignored files
//! - **Cross-language Support**: Handles mixed-language projects
//!
//! # Supported Languages
//!
//! - Rust (.rs)
//! - Python (.py)
//! - JavaScript/TypeScript (.js, .ts, .jsx, .tsx)
//! - Java (.java)
//! - Kotlin (.kt)
//! - C/C++ (.c, .cpp, .h, .hpp)
//!
//! # Example
//!
//! ```no_run
//! use pmat::services::project_analyzer::Project;
//! use std::path::Path;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let project = Project::new(Path::new("./src"))?;
//!
//! // Get all source files in the project
//! let source_files = project.source_files();
//! println!("Found {} source files", source_files.len());
//!
//! // Build dependency graph for analysis
//! let dependency_graph = project.build_dependency_graph().await?;
//! println!("Graph has {} nodes and {} edges",
//! dependency_graph.nodes.len(),
//! dependency_graph.edges.len());
//!
//! // Analyze specific aspects
//! for file in source_files.iter().take(5) {
//! println!(" - {}", file.display());
//! }
//! # Ok(())
//! # }
//! ```
