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)

+# [[W3CSS Sidebar]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+"Open over content" and "slide content to the right" are NOT the same interaction despite looking similar — the former only toggles the sidebar's own `display`, while the latter additionally animates the MAIN content's `margin-left`, meaning a push-style sidebar requires coordinating two separate elements' styles in the same JS function, not just revealing the sidebar itself. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`w3-sidebar`** — the base class for a vertical, typically fixed-position side navigation panel. [S1]
+- **Six distinct sidebar interaction patterns** — always-visible, collapsible-responsive, overlay-over-part, overlay-over-all, slide-content-right, and right-side instead of left. [S1]
+- **`margin-left` reservation** — an always-visible sidebar requires the adjacent content div to have a matching `margin-left` (e.g. sidebar `width:25%` pairs with content `margin-left:25%`) so content doesn't render underneath it. [S1]
+- **`w3-collapse`** — combined with `w3-hide-large`, creates a sidebar that's always visible on large screens but hidden/toggle-controlled on small screens. [S1]
+- **`w3-overlay`** — adds a semi-transparent (50% opacity) black layer over page content while the sidebar is open, visually emphasizing the open sidebar without changing its position. [S1]
+- **Right-side placement** — simply swapping `style="left:0"` for `style="right:0"` (or omitting `left` and adding `right:0`) relocates the entire sidebar system to the opposite edge. [S1]
+
+## 📖 세부 내용 (Details)
+- Always-visible sidebar with reserved content margin: `<div class="w3-sidebar w3-bar-block" style="width:25%">...</div><div style="margin-left:25%">... page content ...</div>`. [S1]
+- Slide-content-right (distinct from simple overlay): `function w3_open() { document.getElementById("main").style.marginLeft = "25%"; document.getElementById("mySidebar").style.width = "25%"; document.getElementById("mySidebar").style.display = "block"; }` — moves BOTH the sidebar and the main content. [S1]
+- Overlay effect: `<div class="w3-overlay" onclick="w3_close()" style="cursor:pointer" id="myOverlay"></div>` shown/hidden alongside the sidebar via the same open/close functions. [S1]
+- Collapsible responsive sidebar: `<div class="w3-sidebar w3-bar-block w3-collapse w3-card" style="width:200px;" id="mySidebar"><button class="w3-bar-item w3-button w3-hide-large" onclick="w3_close()">Close &times;</button>...</div>` paired with a `w3-main` content div using matching `margin-left`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **오버레이 vs 콘텐츠 밀기의 차이**: 단순 오버레이는 사이드바의 display만 바꾸지만, "슬라이드" 방식은 사이드바뿐 아니라 메인 콘텐츠의 marginLeft까지 함께 변경해야 한다는 구현 차이가 있음. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — w3-overlay로 사이드바 오픈 시 배경을 어둡게 처리해 시선을 집중시키는 패턴이 모바일 메뉴 UX의 대표 실전 기법이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Sidebar with a semi-transparent overlay over the page content (HTML/JS):
+```html
+<div class="w3-sidebar w3-bar-block" style="display:none;z-index:5" id="mySidebar">
+  <button class="w3-bar-item w3-button" onclick="w3_close()">Close</button>
+  <a href="#" class="w3-bar-item w3-button">Link 1</a>
+</div>
+<div class="w3-overlay" onclick="w3_close()" style="cursor:pointer" id="myOverlay"></div>
+<script>
+function w3_open() {
+  document.getElementById("mySidebar").style.display = "block";
+  document.getElementById("myOverlay").style.display = "block";
+}
+function w3_close() {
+  document.getElementById("mySidebar").style.display = "none";
+  document.getElementById("myOverlay").style.display = "none";
+}
+</script>
+```
