fix: adapt native fast preload for current Codex

[yinsang0910-star]

中文说明

这个 PR 把原生 Fast / service-tier preload 修复迁移到 Codex++ v1.2.21，并额外适配当前 Codex 26.623 系列。

修复内容：

• 修复 API Key 登录模式下 Codex 原生 Fast / service-tier 不显示或不生效的问题。
• Windows Store packaged Codex 启动时，改用直接启动 packaged Codex.exe 的方式传入 NODE_OPTIONS，避免 preload 丢失。
• 更新 service-tier asset patch 模式，适配当前 Codex 26.623 资源，版本标记为 protocol-handle-4。

本地验证：

• 从补丁版 Codex++ 启动 Codex 后，Fast 模式已出现并可启用。
• protocol-handle-4 preload 成功加载。
• 两个原生 service-tier asset 都成功 patch，没有 service_tier_preload_asset_patch_failed。

Summary

Rebase the native Fast / service-tier preload fix onto Codex++ v1.2.21 and adapt it for current Codex 26.623 builds.

Changes:

• Fix native Fast / service-tier visibility and behavior for API-key auth.
• Preserve NODE_OPTIONS on Windows Store packaged Codex launches by using a direct packaged executable launch when the preload is enabled.
• Update the preload asset patch patterns for current Codex 26.623 service-tier bundles, using protocol-handle-4.

• Local isolated Codex run logged protocol-handle-4 service_tier_preload_asset_patched for both service-tier assets.

Local verification on Windows with Codex 26.623.5546.0:

• Launching Codex from the patched Codex++ build exposes Fast mode.
• protocol-handle-4 preload loads successfully.
• Both native service-tier assets are patched without service_tier_preload_asset_patch_failed.
