1/2 Heart Mod

• Added a per-player /halfheart <true|false> command. Enabling it clamps incoming damage so your health never drops below half a heart; disabling it restores normal deaths.
• The toggle is stored on the player and re-applies on login/respawn. Leaving or dying will not clear it unless you run /halfheart false.
• Only the executing player can toggle their own protection; the command is available on both client and dedicated servers.
• Lethal hits are reduced instead of canceled, so players still take damage up to the half-heart floor. Direct health changes that bypass damage events are not intercepted.
