补齐 Astra 元数据与 Max/Ultra 支持 / Add Astra metadata and reasoning efforts

问题与范围

gpt-6-astra 尚未进入内置兼容元数据查询，使用自定义供应商时会回落到通用模型信息，缺少原生 max / ultra 推理档位。用户已通过本地 catalog 配置验证这两个档位可用；此 PR 将对应元数据单独补齐。

• 新增 Astra 元数据：low / medium / high / xhigh / max / ultra，默认 medium，默认上下文窗口 272K。
• 补齐 Fast 能力：additional_speed_tiers: ["fast"]，沿用现有 priority service tier，使 catalog 与 UI 元数据一致。
• 复用现有 catalog 生成与 UI descriptor 元数据通路，无窗口后缀、无 model list 时也能为当前 Astra 模型生成 catalog。
• 保留显式窗口覆盖及其他模型行为；仅精确匹配 gpt-6-astra，不猜测别名。
• 不新增推理控件、代理或请求重写，不改安装流程，不包含其他功能。

推理能力字段依据本地工作的兼容配置；272K 为本补丁的默认值。未将这些兼容值宣称为独立核验的官方模型规格。Responses Lite 保持关闭。

Fast 能力依据 OpenAI Fast mode 文档：请求接受 service_tier: "fast" 或兼容值 "priority"。本补丁沿用 Codex++ 现有 priority 通路，不修改请求逻辑。官方注明 Astra 的 Fast 不包含延迟 SLA，且不支持 EU 数据驻留；第三方供应商仍需自行支持此能力。

验证

cargo test --offline -q -p codex-plus-core --test model_suffix --test relay_config -j 2 -- --test-threads=1

• model_suffix: 16 passed
• relay_config: 146 passed
• git diff --check: passed

覆盖 catalog/UI 六档及 Fast 能力一致性、272K 默认值、显式窗口覆盖、未知别名隔离及 PureApi 自动生成 catalog。未安装此分支产物，也未重新验证真实 API 请求；真人验证来自已有本地配置。

English

Add an exact-match Astra compatibility metadata entry through the existing catalog and UI metadata lookup. Expose native max and ultra alongside low/medium/high/xhigh, with a medium default and a 272K default context window.

This is a metadata-only fix: no new reasoning controls, request rewriting, proxy behavior or installation changes. Explicit window overrides and existing model behavior remain intact. Capability values follow a locally working catalog configuration, not independently verified official model specifications; the user's personal 300K override is deliberately excluded.

Fast support is separately verified against the official Fast mode guide, which accepts both fast and priority. Declare additional_speed_tiers: ["fast"] and reuse the existing priority service tier. Astra Fast has no latency SLA and is unavailable with EU data residency; third-party provider support is still required.

Validation: 16 model-suffix tests and 146 relay-config tests pass, including catalog/UI effort and Fast parity and no-suffix PureApi catalog generation. git diff --check passes. No build from this branch was installed and no fresh real API request was tested.
