Donut RTP

Added

• HeadDatabase ID support — GUI items can use a HeadDatabase head via material: "hdb-<id>" (requires HeadDatabase plugin). Existing material and head block formats are unchanged.
• Action bar cooldown sound — Optional sound played each second during the warmup countdown (actionbar-cooldown in config.yml). Disabled by default for backwards compatibility.
• Instant teleport option — Set instant-teleport: true to skip the warmup countdown and teleport immediately after a safe location is found.

Configuration

• New instant-teleport key in config.yml (default: false)
• New actionbar-cooldown section in config.yml (see inline comments for examples)
• HeadDatabase example under gui.items in config.yml
• Missing config keys are backfilled with sensible defaults on reload

Added

• Configurable GUI items Per-world RTP buttons (Overworld, Nether, End) can be customized in config.yml:
  • Slot, display name, and lore
  • Any valid Minecraft material as the icon
  • Custom player heads via texture hash, full base64 value, UUID, or player name
• Configurable teleport sound Play a sound on successful RTP with adjustable volume and pitch (teleport-sound in config.yml)
• Action bar warmup countdown Remaining seconds are shown on the action bar during the teleport warmup (configurable via countdown-actionbar in messages.yml)

Changed

• Warmup countdown no longer spams chat each second; the "don't move" warning still appears once in chat
• Invalid materials, player heads, sounds, or GUI slots log a console warning and fall back to defaults

Configuration

• New gui.items section in config.yml (see inline comments for examples)
• New teleport-sound section in config.yml
• New countdown-actionbar key in messages.yml

• fixed TP on Folia didn't work properly.
