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.

+# [[C Boolean Examples]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+This chapter explicitly reframes the entire preceding Comparison/Boolean material as mere PREPARATION for `if...else` — printing a raw `1` or `0` (as done in every earlier example) is functionally correct but not directly useful to an end user, and the source's own upgrade (wrapping the same comparison in `if (myAge >= votingAge) {...} else {...}`) shows that booleans are the evaluated CONDITION inside control flow, not typically an end product to display as-is. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Comparison as raw output** — printing a comparison directly (`printf("%d", myAge >= votingAge);`) shows 1 or 0, technically correct but not user-friendly. [S1]
+- **Comparison as an `if` condition** — the SAME comparison expression, placed inside `if (...)`, drives which branch of code executes, producing human-readable output instead of a raw 1/0. [S1]
+- **Booleans as the foundation of conditions** — the chapter explicitly states booleans "are the basis for all comparisons and conditions," directly foreshadowing the next chapter's Conditions/if-else content. [S1]
+
+## 📖 세부 내용 (Details)
+- Raw comparison output: `int myAge = 25; int votingAge = 18; printf("%d", myAge >= votingAge); // Returns 1 (true)`. [S1]
+- The same logic upgraded into an if...else: `if (myAge >= votingAge) { printf("Old enough to vote!"); } else { printf("Not old enough to vote."); }`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+투표 가능 연령(18세) 확인 로직을 raw 1/0 출력에서 if...else로 업그레이드하는 것이 이 챕터가 직접 보여주는 실전 활용 사례이자, 다음 챕터(Conditions)로의 전환점이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+The same boolean comparison used inside an if...else for human-readable output (C):
+```c
+int myAge = 25;
+int votingAge = 18;
+if (myAge >= votingAge) {
+  printf("Old enough to vote!");
+} else {
+  printf("Not old enough to vote.");
+}
+```

+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.83
+- **중복 검사 결과:** 신규 생성 (New discovery)

+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[C Tutorial]]
+- **관련 개념:** [[C Booleans]], [[C Conditions]]
+- **참조 맥락:** 불리언 섹션 마지막 — 조건문(Conditions) 섹션으로 직접 이어짐.
