Rejoin Scheduler (Catporter utilities)

A reconnect can be scheduled with a command that sets the delay in seconds, or with a named preset that keeps the delay for later use. Presets are saved as JSON files inside the config folder, so a player can keep separate presets for different scenarios, such as a short restart or a longer maintenance window. Subcommands for setting delays, managing presets and enabling a rejoin can be adjusted quickly. Because the scheduling happens on the client, no server-side setup is needed.

The mod is built to work alongside the Catporter utilities, whose cat entity tracks a player's position. A Catporter mechanic may require the player to be offline during a specific window, for example between 10 and 20 seconds, and to rejoin within that time. Rejoin Scheduler helps reliably hit that timing window, since a delay can be converted from seconds to game ticks, where 20 ticks make one second, so a 15 second delay is 300 ticks. The mod is client-side only, so it changes nothing on a server and servers run without it.
