robit-ai 0.1.3

//! Configuration loading for config.toml.
//!
//! Loads a single unified config file from:
//!   1. `cwd/.robit/config.toml` (project-local, highest priority)
//!   2. `~/.robit/config.toml`   (global fallback)
//!
//! Configuration format uses a providers + models structure:
//! ```toml
//! default_model = "deepseek/deepseek-chat"
//!
//! [providers.deepseek]
//! name = "DeepSeek"
//! base_url = "https://api.deepseek.com/v1"
//! api_key = "${DEEPSEEK_API_KEY}"
//!
//! [[providers.deepseek.models]]
//! id = "deepseek-chat"
//! context_window = 65536
//! ```
//!
//! Environment variable substitution is supported in `api_key` fields via `${ENV_VAR}` syntax.
