/**
 * adapters/codex — Codex CLI platform adapter.
 *
 * Implements HookAdapter for Codex CLI's JSON stdin/stdout paradigm.
 *
 * Codex CLI hook specifics:
 *   - 5 hook events: PreToolUse, PostToolUse, SessionStart, UserPromptSubmit, Stop
 *   - Same wire protocol as Claude Code (JSON stdin → stdout)
 *   - Config: ~/.codex/hooks.json + ~/.codex/config.toml (TOML for MCP/features)
 *   - Session dir: ~/.codex/context-mode/sessions/
 *
 * IMPORTANT: Hook dispatch is NOT yet active in Codex CLI (v0.118.0).
 * codex_hooks feature flag is Stage::UnderDevelopment — hooks are implemented
 * in codex-rs/hooks/ but not wired into the tool execution pipeline.
 * Our adapter is ready; it will work once Codex enables dispatch.
 * Track: https://github.com/openai/codex/issues/16685
