[Child #13] world drawing buffer와 seal 유지시간 튜닝

[SilverSupplier]

Parent: #13

목적

우클릭 world casting의 0.8초 stroke buffer와 seal lifetime이 실제 손맛에 맞는지 조정한다.

해야 할 일

• 바람 3획 입력에서 buffer가 너무 짧거나 긴지 확인한다
• overlay를 붙이기 전에 base seal이 사라지는지 확인한다
• bufferSeconds, minPointDistance, seal duration 후보 값을 테스트한다
• 테스트 결과에 따라 기본값을 조정한다

주요 파일/대상

• unity/MagicExamHall/Assets/MagicExamHall/Scripts/Runtime/WorldDrawingController.cs
• unity/MagicExamHall/Assets/MagicExamHall/Scripts/Core/SpellRuntime.cs
• unity/MagicExamHall/Assets/MagicExamHall/Scripts/Runtime/ExamGameController.cs

완료 조건

• 다획 입력이 버튼 없이 안정적으로 가능하다
• overlay 부착 시간이 너무 촉박하지 않다
• PlayMode tests가 계속 통과한다

Implementation update is now on PR #11 in commit d5f82c6.

Covered here:

• world drawing buffer default tuned from 0.8s to 1.05s
• seal duration default tuned from 7.5s to 11s
• runtime applies playable defaults so the existing scene does not keep stale serialized timing values
• scene builder applies the same defaults for rebuilt scenes
• regression tests now assert the tuned world drawing defaults and seal lifetime

Verification:

• Unity EditMode: 20 passed / 0 failed
• Unity PlayMode: 6 passed / 0 failed
• docs validation via bundled node: passed

Leaving #35 open until PR #11 is merged.

Correction/final link: PR #11 was merged while this timing work was being prepared, so the actual implementation PR for this issue is now #58.

Final implementation branch/commit:

• PR: Feat: tune Magic Exam Hall world casting timing #58
• commit: 41dba0f

The PR body includes Closes #35, so this issue should close when #58 is merged.
