This crate handles loading, parsing, and persisting configuration settings. It uses a hierarchical approach, allowing global user settings to be overridden by project-specific configurations and environment variables.

Features

Hierarchical Configuration: Merges defaults, user config, project config, and env vars.
Strong Typing: Provides a type-safe Settings struct for application-wide use.
Provider Preferences: Manage model selections and provider-specific URLs.
Permission Mapping: Integrates with the permissions crate to define tool-use policies.

Usage

Configuration is typically loaded via load_settings(), which looks for:

~/.config/owlen/config.toml (Global)
<project_root>/.owlen.toml (Project-specific)
OWLEN_* environment variables (Overriding)
