// socket.reef — Unix domain socket server for zygctl communication
//
// Listens on /var/run/zyginit.sock for commands from zygctl.
// Protocol: newline-delimited text commands, JSON responses.
//
// Commands:
//   status              → list all services and their states
//   status <name>       → status of a single service
//   start <name>        → start a service (transient, not persisted)
//   stop <name>         → stop a service
//   restart <name>      → stop then start
//   enable <name>       → create symlink in enabled.d/ (persisted)
//   disable <name>      → remove symlink from enabled.d/
//   list                → list all known service definitions
