/** Configuration Loader for MCPC CLI
 *
 * This module provides utilities to load MCPC configuration from command-line arguments,
 * environment variables, or files.
 *
 * Command-line arguments:
 * - `--config <json>` - Inline JSON configuration string
 * - `--config-url <url>` - Fetch configuration from URL (e.g., GitHub raw)
 * - `--config-file <path>` - Path to configuration file
 * - No arguments - Uses ./mcpc.config.json if available
 *
 * Environment variables:
 * - `MCPC_CONFIG` - Inline JSON configuration string (same as --config)
 * - `MCPC_CONFIG_URL` - URL to fetch configuration from (same as --config-url)
 * - `MCPC_CONFIG_FILE` - Path to configuration file (same as --config-file)
 *
 * Priority order:
 * 1. --config (inline JSON)
 * 2. MCPC_CONFIG environment variable
 * 3. --config-url or MCPC_CONFIG_URL
 * 4. --config-file or MCPC_CONFIG_FILE
 * 5. ~/.mcpc/config.json (user config)
 * 6. ./mcpc.config.json (local config)
 *
 * @example
 * ```bash
 * # Inline JSON config
 * deno run --allow-all src/bin.ts --config '[{"name":"my-agent","description":"..."}]'
 *
 * # Using environment variable
 * export MCPC_CONFIG='[{"name":"my-agent","description":"..."}]'
 * deno run --allow-all src/bin.ts
 *
 * # From URL
 * deno run --allow-all src/bin.ts --config-url https://example.com/config.json
 *
 * # From file
 * deno run --allow-all src/bin.ts --config-file ./my-config.json
 *
 * # Default (uses ./mcpc.config.json)
 * deno run --allow-all src/bin.ts
 * ```
