enact-config 0.0.2

//! Enact Configuration Management
//!
//! Unified configuration management for Enact with:
//! - Environment variable support for secrets (checks `ENACT_*` env vars first)
//! - OS keychain for secrets (API keys, tokens, credentials) with fallback support
//! - Encrypted file storage for settings (feature flags, timeouts, preferences)
//! - Cloud sync for authenticated users (respects air-gapped mode)
//!
//! # Example
//!
//! ```rust,no_run
//! use enact_config::{ConfigManager, RuntimeMode, default_config_path};
//!
//! # async fn example() -> anyhow::Result<()> {
//! let config_path = default_config_path()?;
//! let manager = ConfigManager::new(config_path).await?;
//!
//! // Load configuration
//! let config = manager.load().await?;
//!
//! // Set a secret (stored in keychain)
//! manager.set_secret("providers.azure.apiKey", "your-api-key").await?;
//!
//! // Set a setting (stored in encrypted file)
//! let mut config = manager.load().await?;
//! config.runtime.mode = RuntimeMode::Local;
//! manager.save(&config).await?;
//!
//! // Save configuration
//! manager.save(&config).await?;
//! # Ok(())
//! # }
//! ```
