fix(tool-cbm-quiet): 修复 wrapper 破坏 0.11 daemon 并清理上游 pi 冲突产物

- 去掉 wrapper 的 `exec -a "codebase-memory-mcp"`：覆盖 argv[0] 会导致
  codebase-memory-mcp >= 0.11 的 daemon rendezvous 失败
  （daemon endpoint held by pid ... answered no rendezvous），普通 exec 即可
  在保留 stderr 重定向的同时保持 daemon 健康。
- 新增步骤 4.5：清理上游 install.sh 为 pi 生成的无 cbm_ 前缀产物
  （extensions/cbmem.ts、全局 AGENTS.md、同名 skill），避免与本项目统一
  使用的 npm:pi-codebase-memory-mcp（cbm_* 前缀）重复注册/命名冲突；
  可用 CBM_KEEP_UPSTREAM_PI=1 跳过。
- CBM_MCP_BIN 写入扩展为 ~/.bashrc + ~/.zshrc（macOS 默认 zsh）。
