Parkour Plugin

Parkour is a modern parkour minigame plugin for Paper/Spigot (1.21) that combines fast runs, automatic highscores, and dynamic spawns. Players can jump straight into a run with `/parkour`, get continuous new jump targets, and view their personal best and the global leaderboard anytime (`/parkour mybest`, `/parkour top`).

The plugin includes an optional backend API (Node.js) for leaderboards/highscores: if the API isn’t running, the plugin still works and falls back to safe defaults (e.g., local values). It also supports an external coordinates API to load spawn coordinates via JSON and update them live using an admin command (`/parkour reloadcoords`).

Features
- Parkour runs with automatic start/end and score tracking  
- Leaderboard & personal best (`top`, `mybest`)  
- Optional Node.js backend for highscores (robust fallback if unavailable)  
- PlaceholderAPI integration for score/top ranks (optional)  
- External spawn coordinates via JSON endpoint + caching + manual reload  
- Admin tools: `test/selftest`, `apistatus`, `restartapi`, `reloadcoords`

Commands
- `/parkour` – start a run  
- `/parkour quit` – quit the current run  
- `/parkour top` – show the top players  
- `/parkour mybest` – show your personal best  
- Admin: `/parkour test`, `/parkour selftest`, `/parkour apistatus`, `/parkour restartapi`, `/parkour reloadcoords`
