1//! # StateBuild - Advanced Application State Initialization
2//!
3//! Builds the application state with dependency injection, telemetry
4//! and feature flag support for different build configurations.
5//!
6//! ## Build Profiles
7//!
8//! - **Debug**: Enhanced validation, state inspection
9//! - **Development**: Reduced validation for faster iteration
10//! - **Telemetry**: Full metrics and tracing export
11//!
12//! ## Defensive Coding
13//!
14//! - Type-safe dependency resolution
15//! - Validation of required capabilities
16//! - Graceful degradation for optional dependencies
