fix(deploy): agent 不再随 server 停 —— 解耦 systemd 依赖(#8 静默掉线根因)

Requires=pangolin-server → Wants=(软依赖);Restart=on-failure → always + StartLimitIntervalSec=0。根因:Requires= 使每次重启 server 都把 agent 一起拖停且不自起 → 节点静默 down。agent 本就靠 gRPC 自重连,不该绑 server 生死。线上 /etc/systemd 已同步 daemon-reload,并重启 server 验证 agent 全程存活+重连。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
