refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조

에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

+# [[PHP Includes]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+`include` and `require` behave identically on SUCCESS but diverge sharply on FAILURE — a missing file only produces a warning with `include` (script continues, later code still runs), while the same missing file with `require` triggers a fatal error that halts script execution entirely, making the choice a statement about how critical that file is to the page working at all. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`include 'file';`** / **`require 'file';`** — insert a file's content into the calling file. [S1]
+- **Failure behavior difference** — `include` → `E_WARNING`, script continues; `require` → `E_ERROR` (fatal), script stops. [S1]
+- **When to use `include`** — non-critical files like headers, footers, navigation menus (page can still render without them). [S1]
+- **When to use `require`** — critical files like configuration or database connections (page is meaningless without them). [S1]
+- **Included files share variable scope** — variables defined in an included file become usable in the calling file. [S1]
+
+## 📖 세부 내용 (Details)
+- Include a footer: `<?php include 'footer.php';?>`. [S1]
+- Include a nav menu: `<div class="menu"><?php include 'menu.php';?></div>`. [S1]
+- Include shares variables: `vars.php` defines `$color='red'; $car='BMW';`; the including file can then `echo "I have a $color $car.";` after `include 'vars.php';`. [S1]
+- include on missing file (continues): `<?php include 'noFileExists.php'; echo "I have a $color $car."; ?>` — the echo still runs (with warning), though `$color`/`$car` are undefined here since the file wasn't found. [S1]
+- require on missing file (halts): `<?php require 'noFileExists.php'; echo "I have a $color $car."; ?>` — the echo NEVER executes; script dies at the require line. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **실패 시 동작의 근본적 차이**: include는 경고만 내고 스크립트가 계속 실행되지만, require는 치명적 에러를 내고 스크립트 실행이 완전히 중단된다는 점이 대비 예제로 직접 증명됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 모든 페이지가 공유하는 표준 헤더/푸터/메뉴 파일을 include로 재사용하는 것이 실전 코드 재사용의 대표 패턴이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+require halts execution on failure, unlike include (PHP):
+```php
+<?php require 'noFileExists.php'; // fatal error — script dies here
+echo "This line never runs.";
+?>
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.90
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[PHP Tutorial]]
+- **관련 개념:** [[PHP Date]], [[PHP Files]], [[PHP Variables Scope]]
+- **참조 맥락:** 코드 재사용을 위한 파일 포함 — 파일 처리(Files) 섹션으로 이어짐.
