Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

CSharp Output

🎯 한 줄 통찰 (One-line insight)

C# splits what C's single printf handled into two separate methods differentiated ONLY by whether a trailing newline is added — WriteLine() (adds newline) vs. Write() (doesn't) — the same two-method split C++ never needed because cout << never auto-newlines (you always add "\n" explicitly), meaning C# occupies a middle ground: less manual than C++'s explicit-newline-every-time model, but still requires picking the right method name up front rather than composing newlines as data. [S1]

🧠 핵심 개념 (Core concepts)

Console.WriteLine() — outputs text/values AND appends a new line after each call. [S1]
Console.Write() — outputs text/values WITHOUT appending a new line; consecutive Write() calls print on the same line. [S1]
Numeric output & inline math — Console.WriteLine(3 + 3); performs the calculation and prints the result directly, no string conversion needed. [S1]
Tutorial convention — the W3Schools C# series uses WriteLine() exclusively going forward, specifically because it makes output easier to read chapter-to-chapter. [S1]
Manual spacing with Write() — since Write() never inserts anything, an extra trailing space must be added manually inside the string when concatenating consecutive Write() outputs for readability. [S1]

📖 세부 내용 (Details)

Multiple WriteLine() calls each produce their own line: Console.WriteLine("Hello World!"); Console.WriteLine("I am Learning C#"); Console.WriteLine("It is awesome!");. [S1]
Write() chaining on one line: Console.Write("Hello World! "); Console.Write("I will print on the same line."); — note the manual trailing space in the first string. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

줄바꿈 여부로 메서드 자체가 분리됨: C++의 cout <<는 줄바꿈을 절대 자동으로 넣지 않고 항상 "\n"을 명시적으로 붙여야 했지만, C#은 아예 WriteLine()/Write() 두 개의 다른 메서드로 나눠 줄바꿈 자동 삽입 여부를 메서드 선택 시점에 결정한다는 점이 확인됨 — C의 printf 하나로 처리하던 것을 두 메서드로 분리한 것. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 여러 줄 출력과 같은 줄 출력을 비교하는 예제가 원문에서 제시됨. [S1]

💻 코드 패턴 (Code patterns)

WriteLine vs Write — the only difference is the trailing newline (C#):

Console.WriteLine("Hello World!");   // newline added automatically
Console.WriteLine(3 + 3);             // prints 6

Console.Write("Hello World! ");       // no newline -- manual space added
Console.Write("I will print on the same line.");
