//! # Task Executor
//!
//! The Task Executor provides task execution via the dispatcher architecture.
//! The scheduler pushes task-ready events to executors, which handle execution
//! with automatic context loading and state management.
//!
//! ## Key Features
//!
//! - **Push-Based Execution**: Scheduler dispatches tasks directly to executors
//! - **Atomic Task Claiming**: Thread-safe task claiming with database locking
//! - **Lazy Context Loading**: Automatic dependency context loading at execution time
//! - **Simple Conflict Resolution**: Latest task wins for key conflicts
//! - **Concurrency Management**: Configurable limits with semaphore-based control
//! - **Timeout Handling**: Per-task execution timeout with cancellation
//!
//! ## Components
//!
//! - `ThreadTaskExecutor`: Default executor implementing the `TaskExecutor` trait
//! - `PipelineExecutor`: Handles pipeline execution results and status tracking
//!
//! ## Configuration
//!
//! The executor can be configured using `ExecutorConfig`:
//! - Concurrency limits (`max_concurrent_tasks`)
//! - Execution timeouts (`task_timeout`)
//!
//! ## Thread Safety
//!
//! All components are thread-safe and can be used in concurrent environments.
