feat(compute): Codex 补充 GPT-5.6 家族并下线三个已停用 -codex 模型 (#57)

* feat(compute): Codex 订阅接入补充 GPT-5.6 家族并下线三个已停用 -codex 模型

新增 gpt-5.6-sol/terra/luna（2026-07-09 发布）、gpt-5.4-mini、
gpt-5.3-codex-spark（ChatGPT Pro 专属研究预览）；将已从 ChatGPT 订阅接入
下线的 gpt-5.3-codex/gpt-5.2-codex/gpt-5.1-codex-mini 移入 tombstones。
presetDataVersion 73 -> 74。

* fix(compute): 补全 Luna 的 reasoning 与 Spark 的 tool_use 能力标签

采纳 Codex review 意见：GPT-5.6 Luna 官方文档确认支持 reasoning token；
GPT-5.3 Codex Spark 官方公告确认可做代码编辑、按需运行测试，属于 tool_use。
