v1.3.17 feat: add SIGHUP hot-reload support, replace restart sequences with reload

- special thanks to @starfendou for the technical guidance on hot reloading. - add `cmd_systemctl reload` subcommand with PID detection (Alpine: pidfile → kill -HUP; systemd: systemctl kill -s HUP) - add OpenRC `reload()` function in sing-box service via start-stop-daemon --signal HUP - replace `restart` with `reload` for config changes (ports, hy2realm, bindinterface, uuid/sni/name) - replace `disable+enable` with `reload` for protocol add/remove and port change flows - replace `restart` with `reload` for custom route add/delete operations - remove unnecessary `sync_firewall_rules` call in hy2bw bandwidth change (only modifies subscribe/proxies, no port changes) - run `sing-box check -C` with the new binary before replacing the running one. abort upgrade early when the new binary rejects the existing config - force base-config regeneration on upgrade to guarantee sing-box check passes v1.3.17 feat: 新增 SIGHUP 热更支持，用 reload 替换重启流程 - 感谢 @starfendou 在热加载（Hot Reloading）技术上给予的指导与支持。 - cmd_systemctl 新增 reload 子命令，支持 PID 检测（Alpine: pidfile → kill -HUP; systemd: systemctl kill -s HUP） - OpenRC 服务脚本新增 reload() 函数，通过 start-stop-daemon --signal HUP 实现热更 - 端口 / hy2realm / 绑定接口 / 通用配置修改改为 reload - 协议增删和端口变更流程从 disable+enable 改为 reload - 自定义路由增删改为 reload - 移除 hy2bw 带宽修改中无意义的 sync_firewall_rules 调用（只改 subscribe/proxies，不涉及端口） - 替换运行中二进制前，先用新内核执行 `sing-box check -C` 预检配置，新内核不兼容现有配置时提前中止升级 - 升级时强制重置基础配置至新版格式，保证兼容性
