### 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`
