Pull request overview

This PR fixes broken section numbering across 12 blog posts, making h2 (##) and h3 (###) headers sequential. The posts had non-sequential numbering (e.g., 1→2→6→10) likely from content reorganization, and this PR corrects them to be sequential (e.g., 1→2→3→4). A total of 134 headers were updated across the 12 files.

Changes:

• Renumbered h2 section headers to be sequential across all 12 posts
• Updated h3 sub-headers to match their parent h2 section numbers
• No content changes — only section numbering was modified

The h2 was renumbered from ## 9 to ## 6, and ### 6.1 was correctly updated. However, the next sub-header at line 532 is still ### 8.2 AI 생성 코드 검증 체크리스트 (old numbering). It should be updated to ### 6.2 to be consistent with the parent ## 6 section.

[Copilot]

The h3 header was renumbered from ### 6.4 to ### 3.4, but the h4 sub-headers directly below it (#### 6.4.1 서울 리전 최적화 at line 502, #### 6.4.2 개인정보 보호법 준수 자동화 at line 504) still reference the old section number 6.4. These should be updated to #### 3.4.1 and #### 3.4.2 respectively to maintain consistency with the parent header.

[Copilot]

The h2 was renumbered from ## 5 to ## 4 and h3 from ### 5.1 to ### 4.1, but the sibling sub-headers immediately below (lines 327-338) — ### 6.2 Network Policy, ### 7.2 Cloud Monitoring, ### 7.3 Security Command Center 통합 — still carry old/inconsistent numbering. These should also be updated to match the parent ## 4 section (e.g., ### 4.2, ### 4.3, ### 4.4).
