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)

+# [[JavaScript Functions]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+A JavaScript function is a reusable block of code designed for a particular task that runs only when it is called — write it once, run it many times. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Functions are reusable code blocks** designed to perform a particular task; they execute when they are called or invoked. [S1]
+- **Why use functions** — to reuse code (write once, run many times) and to organize code into manageable sections. [S1]
+- **Declaration syntax** — the `function` keyword, a name, a parenthesized parameter list, and a body in curly braces. [S1]
+- **Functions run when called** — the code inside runs only when something invokes the function with `()`. [S1]
+- **Local variables** — variables declared inside a function can only be accessed from within it; they are created when the function starts and deleted when it completes. [S1]
+- **Functions used as variables** — a function call can be used anywhere a value is expected, including inside string concatenation. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Define → call** — declare a named function, then invoke it by name with parentheses to run its body. [S1]
+- **Parameterize for reuse** — accept parameters so the same function works on different inputs (`add(5, 5)`, `add(50, 50)`). [S1]
+- **Call as a value** — substitute a function call directly into an expression instead of storing it first. [S1]
+
+## 📖 세부 내용 (Details)
+**Functions are Code Blocks** — functions are reusable code blocks designed to perform a particular task; they execute when they are called or invoked. [S1]
+
+**Why Use Functions?** — functions let you reuse code (write once, run many times) and organize code into manageable sections. [S1]
+
+**JavaScript Function Syntax** — a function is defined with the `function` keyword, a name, parameters in parentheses, and a body in curly braces: [S1]
+```javascript
+function name( p1, p2, ... ) {
+  // code to be executed
+}
+```
+
+**What Does a Function Look Like?** — a basic function declaration: [S1]
+```javascript
+function sayHello() {
+  return "Hello World";
+}
+```
+
+**Functions Run When You Call Them** — the function body runs when it is invoked, and its returned value can be stored: [S1]
+```javascript
+function sayHello() {
+  return "Hello World";
+}
+
+let message = sayHello();
+```
+
+A function with parameters: [S1]
+```javascript
+function multiply(a, b) {
+  return a * b;
+}
+```
+
+**A Function Can Be Used Many Times** — the same definition is reused with different arguments: [S1]
+```javascript
+function add(a, b) {
+  return a + b;
+}
+
+let sum1 = add(5, 5);
+let sum2 = add(50, 50);
+```
+
+**Local Variables** — variables declared inside a function can only be accessed from within the function; they are created when the function starts and deleted when it completes: [S1]
+```javascript
+// code here can NOT use carName
+
+function myFunction() {
+  let carName = "Volvo";
+  // code here CAN use carName
+}
+
+// code here can NOT use carName
+```
+
+**Functions Used as Variables** — a function call can be used directly inside an expression: [S1]
+```javascript
+let x = toCelsius(77);
+let text = "The temperature is " + x + " Celsius";
+```
+And the call can be inlined directly: [S1]
+```javascript
+let text = "The temperature is " + toCelsius(77) + " Celsius";
+```
+
+## 🛠️ 적용 사례 (Applied in summary)
+The page's own snippets are the canonical applied examples — `sayHello()`, `multiply(a, b)`, the reusable `add(a, b)`, the local-variable `myFunction()`, and the `toCelsius(77)` usage inside a string. No external project/commit applications found in the source.
+
+## 💻 코드 패턴 (Code patterns)
+Declare and call a function (language: JavaScript):
+```javascript
+function sayHello() {
+  return "Hello World";
+}
+
+let message = sayHello();
+```
+Reuse with parameters:
+```javascript
+function add(a, b) {
+  return a + b;
+}
+
+let sum1 = add(5, 5);
+let sum2 = add(50, 50);
+```
+Use a function call as a value:
+```javascript
+let text = "The temperature is " + toCelsius(77) + " Celsius";
+```
