Fix: preserve skill names across language changes

Fix: Skill names lost after language change

Problem

When a skill is registered via SkillManager.AddSkill() with a literal string for Name (e.g., Name = "Level") instead of a localization token, the skill displays correctly on initial load. However, after the user changes the game language, the skill name becomes [skill_XXXXXXX] (the internal skill ID).

Root Cause

SkillManager.RegisterCustomSkills() was adding skill translations directly to Localization.instance:

Localization.instance.AddWord($"skill_{skill.UID}", skill.LocalizedName);

When the game language changes, Localization.SetupLanguage() clears and rebuilds the localization dictionary. The LocalizationManager patch re-adds translations from CustomLocalization objects, but skill translations were never stored there—they were lost.

Fix

Changed to use LocalizationManager.Instance.JotunnLocalization.AddTranslation(), which stores translations in the CustomLocalization system. This ensures translations persist and are re-applied after language changes.

LocalizationManager.Instance.JotunnLocalization.AddTranslation($"skill_{skill.UID}", skill.LocalizedName);This follows the same pattern used by PieceManager for category translations.

Testing

1. Register a skill with a literal name: Name = "Level"
2. Verify skill displays correctly
3. Change game language in settings
4. Verify skill name is preserved (previously showed [skill_XXXXXXX])
