DolphinCare

## How it works Two mechanisms, deliberately layered: 1. **Primary — reset the timers.** A dolphin dies from two independent countdowns: its **air supply** (it breathes air, so it drowns if it can't surface) and its **moistness** (2400 ticks, which drains when it's out of water). Every 2 seconds the plugin refills both on every loaded dolphin, so neither ever reaches zero. 2. **Safety net — cancel the damage.** An `EntityDamageEvent` listener cancels `DROWNING`, `DRYOUT`, and `SUFFOCATION` for dolphins, in case a timer slips through between top-ups (e.g. right after a chunk loads). Plus: dolphins are marked **persistent** (`setRemoveWhenFarAway(false)`), because by default they despawn when no player is nearby — which would otherwise empty your tank while you're away. Timers are refreshed on `EntityAddToWorldEvent` too, which fires on both spawn and chunk load, so a dolphin in an unloaded aquarium is fine the moment it loads back in.
