3//! # StateBuild - Advanced Application State Initialization
4//!
5//! Builds the application state with dependency injection, telemetry
6//! and feature flag support for different build configurations.
7//!
8//! ## Build Profiles
9//!
10//! - **Debug**: Enhanced validation, state inspection
11//! - **Development**: Reduced validation for faster iteration
12//! - **Telemetry**: Full metrics and tracing export
13//!
14//! ## Defensive Coding
15//!
16//! - Type-safe dependency resolution
17//! - Validation of required capabilities
18//! - Graceful degradation for optional dependencies
