Full source and runtime modernization focused on safe persistence, predictable reloads, and compatibility with current Paper releases.

Highlights:
• One JAR for Paper 1.21.1–1.21.11 and 26.1.1–26.3
• Atomic heart transfers and data-file replacement
• Coalesced asynchronous disk writes
• Faster indexed team lookups
• Expanded friendly-fire protection
• Reliable task, cache, invite, scoreboard, and sound-cooldown cleanup
• Cached action-bar and sound configuration
• Safer administration and team-name validation
• Fixed join initialization and duplicate respawn teleport behavior

Existing 2.4.x data.yml files stay compatible. Back up the server, replace the old JAR, and restart. Java 21 is required for Paper 1.21.x; Paper 26.x requires Java 25.
