/**
 * Codex CLI process driver for AgentLink.
 *
 * MVP integration:
 * - Each turn spawns `codex exec --json` (or `codex exec resume --json`)
 * - Prompt is written to stdin to avoid command-line length limits
 * - Codex thread_id is used as the AgentLink session id
 * - JSONL stdout is translated into backend_event messages
 * - Session history is read from ~/.codex/sessions/YYYY/MM/DD/*.jsonl
