AX Agent 코드 메시지 강조와 Git 요약 배너 개선

- Cowork/Code 메시지 마크다운 렌더에 camelCase, PascalCase, snake_case 등 코드 심볼 강조를 추가함

- 코드 탭 입력부 위에 저장소/브랜치/변경 수치 요약 배너를 추가해 claude-code 스타일의 repo context를 빠르게 확인할 수 있게 함

- README와 DEVELOPMENT 문서를 2026-04-06 20:18 (KST) 기준으로 갱신함

- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\verify\ -p:IntermediateOutputPath=obj\verify\ (경고 0, 오류 0)

   - 다른 앱에서 타이핑할 때도 AX Copilot가 키 입력 훅 경로에서 과하게 개입하던 부분을 줄였다. [InputListener.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Core/InputListener.cs)는 이제 모든 키다운마다 시스템 파일 대화상자 판정을 하지 않고, 실제 핫키 메인 키·캡처 메인 키·키 필터가 필요한 경우에만 억제 창 검사를 수행한다.
   - [SnippetExpander.cs](/E:/AX%20Copilot%20-%20Codex/src/AxCopilot/Core/SnippetExpander.cs)는 추적 중이 아닐 때 `;` 시작 키 외에는 즉시 반환하도록 바꿨다. 이전에는 일반 타이핑 중에도 모든 키마다 `Ctrl/Alt/Shift` 상태를 읽고 버퍼 로직을 거쳤는데, 이제는 실제 스니펫 시작 상황에서만 그런 검사를 하게 되어 글로벌 키보드 훅의 평상시 부담을 줄였다.

+- AX Agent 메시지 마크다운 렌더에 코드 심볼 강조를 추가해 Cowork/Code 답변의 파일 경로·camelCase/PascalCase·snake_case가 더 선명하게 보이도록 조정했다.
+- 코드 탭 입력부 위에 저장소/브랜치/변경 수치를 보여주는 Git 요약 배너를 추가해 `claude-code` 스타일의 repo context를 더 빠르게 읽을 수 있게 맞췄다.

 - Document update: 2026-04-06 18:34 (KST) - `SnippetExpander.cs` now short-circuits immediately for normal typing unless snippet tracking is already active or the current key is the `;` trigger. This removes repeated `GetAsyncKeyState` and buffer logic from ordinary typing in other apps and makes the low-level hook substantially lighter under continuous input.

+- Improved AX Agent markdown rendering for Cowork/Code by highlighting file paths plus code-like symbols, and added a compact repository summary banner above the Code composer to surface branch and diff context closer to `claude-code`.
