原石の鳴獰: Lock declared names after successful resolution until opponent’s End Phase

[vuryleo]

Description

This PR fixes an issue where 原石の鳴獰 could repeatedly resolve using the same declared monster name within the same turn window.

Intended behavior:

• The card can be activated and a monster name can be declared as normal.
• Once a declared code has successfully resolved, that code is treated as used.
• While a code is used:
  • it cannot be declared again on subsequent activations, and
  • if referenced again at resolution time (e.g. within the same chain), the effect does not resolve.
• The restriction persists until the end of the opponent’s turn, at which point the used-code state is cleared.

Testing

Scenario 1

• Activate 原石の鳴獰, declare a valid Normal Monster code, and let it resolve.
• Activate again and confirm the same code cannot be declared.
• After the opponent’s End Phase, confirm the code can be declared again.

Scenario 2

• With an empty field, activate 原石の鳴獰 and declare a valid Normal Monster code.
• Chain another 原石の鳴獰 declaring the same code; resolve without Special Summon.
• Resolve the first 原石の鳴獰 and confirm no Special Summon occurs.
