Build and Deploy / build-and-push (push) Successful in 54s
- Move MCP tools registration to internal/mcp - cmd/mcp now only contains CLI entry logic - Support env vars TASKPOOL_URL/TASKPOOL_TOKEN for stdio mode - Remove duplicate client.go from cmd/mcp

核心能力：
|
||
- 任务：列表/详情/创建/更新/删除/启停执行
|
||
- 脚本：列表/详情/创建/更新/删除
|
||
- 环境变量：列表/详情/创建/更新/删除（secret 值为脱敏）
|
||
- 日志：列表/详情、最近执行结果
|
||
|
||
使用原则：
|
||
1. 先 list_tasks / get_task 确认目标，再 run_task
|
||
2. 删除类操作前向用户确认
|
||
3. 不要编造任务 ID；ID 以 list/get 返回为准
|
||
4. 执行后用 list_logs 或 get_log 查看结果
|
||
5. 创建任务时 command 必填（普通任务）；schedule 使用标准 cron`
