feat(minigames): add modular queue + interval minigame framework

[JARVIS-AT-ROOTCAUSED]

Summary

Adds a modular minigame system with queue + interval-triggered sessions.

Included

• MinigameManager (core queue/session/config logic)
• MinigameCommand (/minigame join|leave|status|forcestart|cancel|config ...)
• MinigameType, MinigameDefinition, MinigameSession
• module config: Minigames/config.yml
• plugin wiring in SupremeCore
• command + admin permission entries in plugin.yml

Spec Coverage

• Configurable min players per minigame type
• Configurable interval in minutes
• Configurable duration per type
• Queue system via command
• Trigger checks threshold before start
• Arena teleport per minigame type
• Lifecycle timer + end handling + return to lobby
• Admin force start / cancel / reload + config adjustments

Notes

• Session timer is shown via action bar countdown.
• Queue is preserved if threshold is not met at trigger time.
• Runtime config changes persist to plugins/SupremeCore/Minigames/config.yml and reload immediately.
