feat(align): align 5h window refresh to cron targets - #3

Conversation
Add an `align` subcommand to manage cron targets (each with a Docker-style short id and its own max-delay budget) and preview upcoming ping/refresh times. `ping --if-5h-full` now does best-effort phase alignment by default, pinging only once the window is full and the aligned time is reached; `--without-align` restores the plain "ping when full" behavior. Targets and per-target max-delay (default 90m) persist to ~/.config/limitping/config.json. Push planned ping timestamps as a new metric for observability.

Summary
align子命令：管理多条 cron 目标，每条带 Docker 风格短 id 和自己的延时预算max-delay（默认 90m），支持add/list/delete <id|前缀>/clear/preview。ping --if-5h-full默认做“尽力而为”的相位对齐：满额且到达对齐时间后才 ping；--without-align关闭对齐，恢复“满额即 ping”。不带 flag 的ping仍是立即执行。~/.config/limitping/config.json；新增limitping_planned_ping_timestamp_seconds指标上报未来 5 次计划 ping 时间。Behavior matrix
