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)

+# [[CPP Comments]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Unlike the C tutorial, which highlighted a historical constraint (single-line `//` comments only became standard in C99), the C++ chapter presents both `//` and `/* */` as equally native from the start with no such caveat — reflecting that C++ never carried C's pre-1999 single-line-comment limitation, since C++ has supported `//` since its earliest standardization. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Single-line comments (`//`)** — text from `//` to end of line is ignored by the compiler. [S1]
+- **Multi-line comments (`/* */`)** — text between the markers is ignored, regardless of line count. [S1]
+- **Stylistic convention** — `//` for short comments, `/* */` for longer ones; entirely up to the developer. [S1]
+
+## 📖 세부 내용 (Details)
+- Single-line comment before code: `// This is a comment cout << "Hello World!";`. [S1]
+- Single-line comment at end of a line: `cout << "Hello World!"; // This is a comment`. [S1]
+- Multi-line comment: `/* The code below will print the words Hello World! to the screen, and it is amazing */ cout << "Hello World!";`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 짧은 주석에는 //, 긴 설명에는 /* */를 쓰는 관행이 C 챕터와 동일하게 권장됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Single-line comment used to explain a line of code (C++):
+```cpp
+cout << "Hello World!"; // This is a comment
+```
