docs(10_Wiki): 위키 구조 정리 — 언어 튜토리얼 카테고리 폴더 제거 + 신규 자산 동기화

Topic_CSS/Topic_HTML/Topic_JavaScript/Topic_Prompt/Topic_Comfyui 등 기존 카테고리 폴더를 정리하고, Topic_Graphic/Dev 등 신규 산출물과 Topics 내부 세션/메모리 기록을 동기화.

+# [[CPP Data Structures]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+C has exactly ONE built-in data structure — the array — and everything else (linked lists, stacks, queues, hash-like maps) must be hand-built from structs and raw pointers; C++'s STL instead ships vector/list/stack/queue/deque/set/map as ready-made template classes, meaning the entire "how do I build a linked list" problem that consumed a whole chapter of Topic_C's Pointers section is simply gone from the C++ mental model — replaced by "which header do I include." [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **STL (Standard Template Library)** — a library of data structures + algorithms bundled with C++, used to store and manipulate data efficiently. [S1]
+- **Containers** — data structures that store data (vector, list, stack, queue, deque, set, map). [S1]
+- **Iterators** — objects used to access elements of a container without knowing its internal layout. [S1]
+- **Algorithms** — functions like `sort()` and `find()` that operate on containers through iterators. [S1]
+- **One header per container** — each container requires its own `#include` (`<vector>`, `<list>`, `<set>`, `<map>`, `<stack>`, `<queue>`), unlike arrays which need no header. [S1]
+- **Choosing a container is a design decision** — the right data structure + algorithm makes a program run faster, especially at scale; the table of 7 containers (Vector/List/Stack/Queue/Deque/Set/Map) each optimize a different access pattern. [S1]
+
+## 📖 세부 내용 (Details)
+- Container comparison table: Vector (array-like, dynamic size, index access), List (sequential, add/remove both ends, no index access), Stack (LIFO, top only), Queue (FIFO, front/back only), Deque (double-ended, index access), Set (unique elements, no index), Map (key/value pairs, access by key). [S1]
+- Minimal vector usage: `vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"}; for (string car : cars) { cout << car << "\n"; }`. [S1]
+- Containers + iterators + algorithms form a triangle: a container without an algorithm to search/manipulate it is not very useful, and an algorithm needs a container to operate on. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **C에는 없는 개념 층위가 통째로 추가됨**: Topic_C에는 "자료구조 챕터"가 존재하지 않았고(배열이 유일한 내장 자료구조), 연결 리스트/스택/큐는 포인터+구조체로 직접 구현하는 예제들이 Pointers 섹션에 흩어져 있었다. C++는 이를 컨테이너+반복자+알고리즘이라는 3층 구조로 라이브러리화했다는 점이 이번 챕터에서 명확히 드러남. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 문자열 vector를 만들고 for-each로 순회하는 패턴이 원문에서 STL 소개 예제로 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Required headers per container, and a first vector example (C++):
+```cpp
+#include <vector>
+#include <list>
+#include <set>
+#include <map>
+#include <stack>
+#include <queue>
+
+vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"};
+for (string car : cars) {
+  cout << car << "\n";
+}
+```
