Disable Jump Crits

Initial public release

• Disables Minecraft's guaranteed airborne / jump critical hits.
• Preserves Zenith Attributes Renewed's stat-based Crit Chance and Crit Damage system.
• Keeps Zenith's existing critical-hit particles.
• Adds a lightweight vanilla critical-hit sound on successful stat-based crits.
• Adds four small client-side electric sparks around the target on successful crits.
• Crit feedback now occurs only after Minecraft confirms the attack actually dealt an accepted damaging hit.
• Prevents false crit sounds and particles when attacking during a target's hurt-resistance / immunity frames.
• No tick handlers, entity scanning, polling loops, or server-side particle spam.
• Tested with Minecraft 1.20.1, Fabric, Zenith Attributes Renewed 1.0.3, and Better Combat 1.8.6.
