Implement BackendAdapter interface with four CLI backends: - ClaudeCodeBackend (extracted from AgentRuntime) - CodexBackend (OpenAI Codex CLI) - GeminiBackend (Google Gemini CLI) - OpenCodeBackend (OpenCode CLI) Add BackendRegistry for resolution/creation via AGENT_BACKEND env var. Refactor AgentRuntime to delegate to BackendAdapter instead of hardcoding Claude CLI. Update GatewayConfig with new env vars (AGENT_BACKEND, BACKEND_CLI_PATH, BACKEND_MODEL, BACKEND_MAX_TURNS). Includes 10 property-based test files and unit tests for edge cases.
