feat(compute): 新增 Claude Opus 5 + 补齐 Claude 系列 effort 档位，presetDataVersion → 85 (#71)

Opus 5 是 Anthropic Opus 系列当前旗舰（1M 上下文 / 128K 输出 / $5·$25 per MTok，
与 Opus 4.8 同价），此前 config-center 完全缺失，用户在模型选择器里看不到它。

变更：
- compute/providers/anthropic.json：新增 claude-opus-5（排在 fable-5 之后、
  opus-4-8 之前）；serverSideWebSearch.fallbackPriority 顺延重排
- compute/providers/anthropic-claude.json：Claude 订阅 provider 同步新增 claude-opus-5
- compute/model-specs/anthropic.json：补 claude-opus-5 与 claude-sonnet-5 规格
  （sonnet-5 此前只有 provider 条目、没有规格）
- 补 extra.reasoning.supportedEfforts：客户端 parseReasoningEffortConfig 只读
  extra.reasoning，原有的顶层 extra.defaultEffort 不被消费，导致 Claude 模型的
  effort 档位在 UI 上始终不可选。按各模型实际支持声明档位（sonnet-4-6 无 xhigh）
- __tests__/validate.test.mjs：WebSearch 允许名单登记 claude-opus-5
- manifest.json：presetDataVersion 84 → 85
