수정 API에서 title 길이를 영속화 전에 제한하십시오.

Community.title은 length = 100으로 제한되지만, CommunityUpdateRequestDTO.title은 공백만 검증합니다. 101자 제목 요청은 editImages()의 S3 업로드/삭제 작업 이후 flush에서 실패할 수 있습니다. DTO에 @Size(max = 100)을 적용하고, editImages() 전 CommunityService.validatePostRequest()에도 같은 길이 검증을 추가하십시오.

수정 예시 
 import jakarta.validation.constraints.NotBlank;
 import jakarta.validation.constraints.NotNull;
+import jakarta.validation.constraints.Size;

-        `@NotBlank` String title,
+        `@NotBlank` `@Size`(max = 100) String title,

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In
`@src/main/java/com/redo/domain/community/dto/req/CommunityUpdateRequestDTO.java`
at line 13, CommunityUpdateRequestDTO의 title에 `@Size`(max = 100)을 추가하고,
CommunityService의 validatePostRequest()에서 editImages()가 실행되기 전에 동일한 최대 길이 검증을
수행하도록 수정하십시오. Community.title의 100자 제한과 일치시키고, 초과 요청은 S3 작업이나 영속화 전에 거부되도록 기존 검증
흐름을 유지하십시오.
