docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

+# [[W3CSS Code]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Real syntax highlighting (`jsHigh`/`htmlHigh`/`cssHigh` classes) is explicitly NOT part of W3.CSS itself — it only activates if the developer separately downloads and includes W3Schools' own `w3codecolor.js` JavaScript library, meaning `w3-code`/`w3-codespan` alone only provide monospace STYLING, while color-coded syntax requires an entirely separate opt-in dependency. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`w3-code`** — displays a block of code in a readable monospaced font (pure CSS, no highlighting). [S1]
+- **`w3-codespan`** — highlights inline code (e.g. within a sentence) using the `<code>` element. [S1]
+- **`jsHigh` / `htmlHigh` / `cssHigh`** — color-highlighting classes that only function if `w3codecolor.js` is separately loaded; otherwise they have no visual effect. [S1]
+- **Separation of styling vs. behavior** — this chapter reinforces a pattern seen elsewhere in W3.CSS: base classes are pure CSS, but advanced behavior (real syntax coloring) requires an external JS library, not baked into the CSS framework. [S1]
+
+## 📖 세부 내용 (Details)
+- Monospaced code block: `<div class="w3-code">fruits[0] = "Banana";</div>`. [S1]
+- Inline code highlight: `The <code class="w3-codespan">html</code> element defines an HTML page.`. [S1]
+- Requires external library for color: `<div class="w3-code jsHigh">.. JavaScript code here</div>` — only colors correctly once `w3codecolor.js` (downloadable from `w3schools.com/lib/w3codecolor.js`) is included on the page. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **w3-code만으로는 색상 강조 불가**: jsHigh/htmlHigh/cssHigh 클래스는 w3codecolor.js 라이브러리를 별도로 로드하지 않으면 아무 효과가 없다는 점이 명시적으로 경고됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 이 문서 자체의 코드 패턴 섹션이 w3-code 클래스의 실전 활용 예시다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Monospaced code display without syntax coloring (HTML/CSS):
+```html
+<div class="w3-code">
+fruits[0] = "Banana";
+fruits[1] = "Apple";
+</div>
+```
+
+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.85
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[W3.CSS Tutorial]]
+- **관련 개념:** [[W3CSS Tooltips]], [[W3CSS Filters]]
+- **참조 맥락:** Code & Miscellaneous 섹션 첫 항목 — 필터(Filters) 챕터로 이어짐.
