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 Methods]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+`static` on a method means it belongs to the CLASS itself, not to any object instance — a distinction the tutorial defers explaining fully until objects are introduced later, but flags immediately since every method example so far uses it. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Method** — a named, reusable block of code that runs only when called; also called a function. [S1]
+- **Purpose** — code reuse: define once, use many times. [S1]
+- **Declaration inside a class** — `static void myMethod() { ... }`. [S1]
+- **`static`** — the method belongs to the class, not an object instance (elaborated later with OOP). [S1]
+- **`void`** — signals no return value. [S1]
+- **Calling** — `myMethod();` — can be called repeatedly. [S1]
+
+## 📖 세부 내용 (Details)
+- Definition: `public class Main { static void myMethod() { // code } }`. [S1]
+- Call and output: `static void myMethod() { System.out.println("I just got executed!"); } public static void main(String[] args) { myMethod(); }`. [S1]
+- Repeated calls: calling `myMethod();` three times inside main prints the message three times. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 코드 재사용의 기본 단위이며, 파라미터/반환값/오버로딩으로 확장된다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Basic method definition and repeated call (Java):
+```java
+public class Main {
+    static void myMethod() {
+        System.out.println("I just got executed!");
+    }
+    public static void main(String[] args) {
+        myMethod();
+        myMethod();
+        myMethod();
+    }
+}
+```

+## ✅ 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 Methods Param]], [[Java Methods Return]], [[Java OOP]]
+- **참조 맥락:** 코드 재사용의 기본 단위 — 파라미터/반환값 챕터로 확장.
