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)

+# [[Java Syntax]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+The filename MUST exactly match the public class name (`Main` → `Main.java`), because Java uses the class name to locate and run the code — a mismatch is a hard error, not a warning. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Every line of runnable code lives inside a class** — class names conventionally start with an uppercase letter. [S1]
+- **Case-sensitive** — `MyClass` and `myclass` are different names. [S1]
+- **Filename must match the class name** — `class Main` must be saved as `Main.java`. [S1]
+- **`main()` method** — required in every Java program; the entry point where execution starts. [S1]
+- **`System.out.println()`** — prints a line of text; `System` is a built-in class, `out` is its output member, `println()` is the print-line method. [S1]
+- **Semicolons required** — every statement must end with `;`. [S1]
+- **Curly braces `{}`** — mark the start/end of a code block. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Filename-class binding is unusually strict** — unlike many languages where filenames are just organizational, Java enforces filename == public class name as a hard requirement for compilation to succeed. [S1]
+
+## 📖 세부 내용 (Details)
+- Basic structure: `public class Main { public static void main(String[] args) { System.out.println("Hello World"); } }`, saved as `Main.java`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — public/static/void 키워드는 이후 OOP 챕터(Modifiers)에서 상세히 다뤄진다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Minimal Java program structure (Java, file: Main.java):
+```java
+public class Main {
+    public static void main(String[] args) {
+        System.out.println("Hello World");
+    }
+}
+```
+
+## ✅ 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:** [[Java Tutorial]]
+- **관련 개념:** [[Java Intro]], [[Java Statements]], [[Java Modifiers]]
+- **참조 맥락:** Java 프로그램의 기본 골격 — public/static/void는 이후 Modifiers 챕터로 이어진다.
