#### Bug Fixes
- **Bot rank colour preserved after restart** — bot display names now always reconstruct from the current LuckPerms prefix + name format on restore; colours are no longer stripped when saving to the database, and a post-restore prefix refresh runs automatically after all bots are re-queued.
- **Join / leave delay timing fixed** — config values (`join-delay` / `leave-delay`) were being multiplied by 20 internally, making all delays 20× too long. Values are now treated as ticks directly as documented (e.g. `max: 20` = 1 second).
- **`/fpp reload` now refreshes all bot prefixes** — LP cache is invalidated and `updateAllBotPrefixes()` is called, so prefix changes take effect immediately without a restart.

#### New Features
- **`/fpp despawn random [amount]`** — removes a random selection of active bots (default 1). Useful for gradual scale-down.
- **Beta version detection** — when the running version is newer than the latest published release, admins see a styled in-game warning identifying the build as a beta. The message is also delivered to admins who join after the check completes, identical to how update-available notifications work.

#### Internals
- Config-version bumped to **25** (housekeeping stamp — no structural changes).
