v0.3.6: 恢复丢失的11个模块 + 接线基础设施

恢复内容：
- quark驱动拆解为7个子模块 (quark-api/auth/share/storage/cleanup/rename/ad-cleanup)
- 工具模块: utils/crypto, utils/logger, utils/proxy-agent
- 配置校验: config/startup-validator
- 接线: main.ts(checkStartup), credential.service.ts(加密Cookie), admin.routes.ts(代理测试)
- quark.driver.ts 从1533行巨兽瘦身到130行壳子
