Replace the 70/30 input/output token estimation from state_5.sqlite with precise parsing of Codex CLI JSONL session logs (~/.codex/sessions/). - Parse event_msg (token_count), turn_context, and session_meta events - Compute exact input/output/cached token deltas from cumulative totals - Reuse session_log_sync table for incremental file scanning - Pre-filter lines with string contains() before JSON deserialization - Add codex_session data source to DataSourceBar with i18n (zh/en/ja)

//! Codex 会话日志使用追踪
|
||
//!
|
||
//! 从 ~/.codex/sessions/ 下的 JSONL 会话文件中提取精确 token 使用数据，
|
||
//! 替代原有的 state_5.sqlite 估算方案。
|
||
//!
|
||
//! ## 数据流
|
||
//! ```text
|
||
//! ~/.codex/sessions/YYYY/MM/DD/*.jsonl → 增量解析 → delta 计算 → 费用计算 → proxy_request_logs 表
|
||
//! ```
|
||
//!
|
||
//! ## 解析的事件类型
|
||
//! - `session_meta` → 提取 session_id
|
||
//! - `turn_context` → 提取当前 model
|
||
//! - `event_msg` (type=token_count) → 提取累计 token 用量，计算 delta
