1.0.3-1.21

Corrected

• Melee cost is now action-based rather than hit-based, so misses are not free.
• Paid attacks receive a short server grace window so an attack that empties the bar can still land.
• Ranged charging uses the configured value as stamina per second; the former hidden 10x multiplier is gone.
• Projectile shield blocks are charged once and only after blocked damage is confirmed.
• Datapack overrides clear and reload correctly on /reload and reject invalid types, IDs, and costs.
• Datapack-defined shields and ranged weapons participate in runtime checks.
• Configured zero costs and attribute reductions can reduce a cost to exactly zero.
• Recovery delays are independently configurable for melee, ranged, and blocking.
• Movement reductions no longer turn a drain into regeneration, and regeneration bonuses no longer create drain-state regeneration.
• Obsolete server-to-client preview networking and its unused stamina fields were removed.
• Dependency and dedicated-server metadata were corrected.
