建立 Codex Office 虛擬辦公室(模擬 + 實況雙模式)

摘要：
以 claude-office 為基底改造的 Codex CLI 版虛擬辦公室:終端機綠 + 冷灰主題、
>_ 游標標誌,實況模式改為監看 ~/.codex/sessions/ 的 rollout transcripts,
依 cwd 將 session 分組成專案顯示。

根本原因：
既有 claude-office 只能監看 Claude Code 活動,Codex CLI 的 session 格式
(rollout JSONL:session_meta / turn_context / event_msg / response_item)
與存放結構(YYYY/MM/DD 日期目錄)完全不同,需要獨立的轉譯器。

影響：
新專案,與 claude-office 並存:web 5182(0.0.0.0)、watch 5181(僅 127.0.0.1),
與 5179/5180 不衝突,可同時常駐 PM2。

修法：
- server/watch.mjs 重寫:遞迴掃描日期目錄、tail 新增位元組、
  由 session_meta/turn_context 的 cwd 分組專案,
  custom_tool_call/function_call/MCP → 工具事件,agent_message/task_complete → 回覆
- 主題改造:constants 配色(石墨綠)、Sora/Manrope/JetBrains Mono 字型、
  >_ 閃爍游標標誌、agents 改為 Codex/Sol/Nova/Mini、工具改為 exec/apply_patch 等
- live.ts 新增 thinking 事件(對應 reasoning),port 5181
