//! # Test Runner Module
//!
//! The core test execution engine for tanu. This module provides the `Runner` struct
//! that orchestrates test discovery, execution, filtering, reporting, and event publishing.
//! It supports concurrent test execution with retry capabilities and comprehensive
//! event-driven reporting.
//!
//! ## Key Components
//!
//! - **`Runner`**: Main test execution engine
//! - **Event System**: Real-time test execution events via channels
//! - **Filtering**: Project, module, and test name filtering
//! - **Reporting**: Pluggable reporter system for test output
//! - **Retry Logic**: Configurable retry with exponential backoff
//!
//! ## Execution Flow (block diagram)
//!

/// # Features
///
/// - **Concurrent Execution**: Tests run in parallel with configurable limits
/// - **Retry Logic**: Automatic retry with exponential backoff for flaky tests
/// - **Event System**: Real-time event publishing for UI integration
/// - **Filtering**: Filter tests by project, module, or test name
/// - **Reporting**: Support for multiple output formats via reporters
/// - **HTTP Logging**: Capture and log all HTTP requests/responses
///
/// # Examples
///
/// ```rust,ignore
/// use tanu_core::{Runner, reporter::TableReporter};

/// let mut runner = Runner::new();
/// runner.capture_http();
/// runner.set_concurrency(8);

/// - Semaphore-based concurrency control
