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)

+# [[CSharp Comments]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+C#'s comment syntax (`//` single-line, `/* */` multi-line) is byte-for-byte identical to C, C++, and Java's — the FIRST chapter in this entire C# series where the answer to "how is this different from what I already know" is simply "it isn't," confirming the Intro chapter's claim of syntactic closeness to the C family in the most literal, zero-abstraction way possible. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Single-line comments (`//`)** — everything from `//` to the end of the line is ignored; usable on its own line before code or appended at the end of a code line. [S1]
+- **Multi-line comments (`/* ... */`)** — everything between the markers is ignored, regardless of how many lines it spans. [S1]
+- **Convention** — `//` for short comments, `/* */` for longer explanatory blocks; purely a style choice. [S1]
+- **Purpose** — explain code for readability, or temporarily disable code during testing. [S1]
+
+## 📖 세부 내용 (Details)
+- Before-line comment: `// This is a comment` followed by `Console.WriteLine("Hello World!");`. [S1]
+- End-of-line comment: `Console.WriteLine("Hello World!"); // This is a comment`. [S1]
+- Multi-line block: `/* The code below will print the words Hello World to the screen, and it is amazing */` followed by the print statement. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **C/C++/Java와 완전히 동일한 주석 문법**: `//`와 `/* */` 문법이 C, C++, Java와 토씨 하나 다르지 않게 동일하다는 점이 확인됨 — Intro 챕터가 주장한 "C 계열과 문법이 가깝다"는 서술이 이번 챕터에서는 차이 없이 그대로 성립하는 첫 사례. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 줄 앞/뒤 단일행 주석과 여러 줄 블록 주석 예제가 원문에서 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Single-line and multi-line comments — identical syntax to C/C++/Java (C#):
+```csharp
+// This is a comment
+Console.WriteLine("Hello World!"); // This is a comment
+
+/* The code below will print the words Hello World
+to the screen, and it is amazing */
+Console.WriteLine("Hello World!");
+```
