/**
 * Codex Conversation Parser for MCP integration.
 *
 * This parser reads conversation history from Codex's storage location
 * (~/.codex/sessions) and converts it to the same format as ConversationParser.
 *
 * Codex stores conversations in a date-hierarchical structure:
 * ~/.codex/sessions/YYYY/MM/DD/rollout-{timestamp}-{uuid}.jsonl
 *
 * Each line in a Codex session file has the structure:
 * {
 *   timestamp: string,
 *   type: "session_meta" | "response_item" | "event_msg" | "turn_context",
 *   payload: { ... }
 * }
 *
 * @example
 * ```typescript
 * const parser = new CodexConversationParser();
 * const result = parser.parseSessions('/Users/username/.codex');
 * console.error(`Parsed ${result.conversations.length} Codex sessions`);
 * ```
