Changelog:

• Fixed monument HP holograms not disappearing after fight end or boss death.
• Fixed boss spawn announcements and countdown flow.
• Fixed /watcherboss start so the 21-second start now works correctly.
• Fixed /watcherboss stop to fully clean the event (boss, monuments, holograms, mobs, effects, tasks).
• Fixed /watcherboss reload so it now reloads both config.yml and messages.yml correctly.
• Fixed world loading issue (world not found) by adding safer world handling and fallback behavior.
• Fixed damage/reward exploit: cancelled hits (like invulnerable boss hits) no longer count for top damage rewards.
• Fixed spawnwatcherboss command registration and behavior (now properly spawns boss instantly).
• PlaceholderAPI is now optional (softdepend) instead of required.

Combat/Mechanic Improvements:
• Last monument lifecycle is more stable (proper activate/deactivate/remove behavior).
• Pig attack now uses configured values correctly (damage, slow, knockback, explosion power).
• Better task cleanup and encounter reset logic to prevent stuck states.

Compatibility:
• Improved cross-version compatibility for modern Spigot versions.
• Target support: 1.16 - 1.21.x (including 1.18, 1.19, 1.20, 1.21).

Recommended for latest servers: use current Paper/Spigot 1.21.x builds and modern Java runtime for your server version.
