fix: 增强 Claude 反代检测对抗能力

基于 Claude Code v2.1.88 源码分析,修复多个可被 Anthropic 检测的差距:

- 实现消息指纹算法(SHA256 盐值 + 字符索引),替代随机 buildHash
- billing header cc_version 从设备 profile 动态取版本号,不再硬编码
- billing header cc_entrypoint 从客户端 UA 解析,支持 cli/vscode/local-agent
- billing header 新增 cc_workload 支持(通过 X-CPA-Claude-Workload 头传入)
- 新增 X-Claude-Code-Session-Id 头(每 apiKey 缓存 UUID,TTL=1h)
- 新增 x-client-request-id 头(仅 api.anthropic.com,每请求 UUID)
- 补全 4 个缺失的 beta flags(structured-outputs/fast-mode/redact-thinking/token-efficient-tools)
- OAuth scope 对齐 Claude Code 2.1.88(移除 org:create_api_key,添加 sessions/mcp/file_upload)
- Anthropic-Dangerous-Direct-Browser-Access 仅在 API key 模式发送
- 响应头网关指纹清洗(剥离 litellm/helicone/portkey/cloudflare/kong/braintrust 前缀头)
