Unified configuration system for the agentic tools ecosystem.

This crate provides:

• [AgenticConfig]: The root configuration type with namespaced sub-configs
• [load_merged]: Two-layer config loading (global + local) with env overrides
• [schema]: JSON Schema generation for IDE autocomplete (Taplo support)
• [validation]: Advisory validation that produces warnings

Configuration Precedence (lowest to highest)

1. Default values
2. Global config (~/.config/agentic/agentic.toml)
3. Local config (./agentic.toml)
4. Environment variables

Example

use agentic_config::{load_merged, AgenticConfig};
use std::path::Path;

let loaded = load_merged(Path::new(".")).unwrap();
println!("Locator model: {}", loaded.config.subagents.locator_model);

for warning in &loaded.warnings {
    eprintln!("Warning: {}", warning);
}
