feat: 整合功能恢复与技能学习闭环(含 ECC v2.1 parity + Opus 4.7 接入 + prompt 工程优化)

主要变更:
- Skill Learning 闭环系统 (9/9 AC)
- Opus 4.7 模型层接入 + adaptive thinking
- Prompt 工程优化 (64 审计测试)
- Agent Teams 简化门控 (默认启用)
- Windows Terminal 后端修复 (EncodedCommand/WT_SESSION)
- TF-IDF 技能搜索精准化 (字段加权/CJK 优化)
- Autonomy 系统 (/autonomy 命令)
- ACP 协议完整实现
- mock.module 泄漏修复 (CI 全绿)
- 152+ lint/type 修复
