"airClearance" in "rule.yml" can now be 0. If "spawn.ruleId" is empty or missing, the default rule uses "airClearance: 0".
Added the "areaEffects" section to "boss.yml": timers can apply effects to players within a radius around the boss either at fixed intervals or within a random interval range, and can also run a particle file from "plugins/hAirdrops/effects/<id>.yml" at the boss position.
Added the "abilities" section to "boss.yml": boss super abilities work on timers. The first ability, "EXPLOSION", launches the boss upward and creates a configurable TNT-like explosion with a delay, center offset, and optional particle effects.
Added the "SELF_HEAL" type to "abilities": the boss can heal itself directly on a timer, with settings for fixed healing, healing based on a percentage of max health, healing based on a percentage of missing health, and a particle effect.
