feat: add prerequisites, offline prerequisite setup and version tabs

- EXE versions: prerequisite list with the built-in catalog, custom
  installers, download link checks and install file analysis; entries
  are added by the user (no automatic adding), one "추가" dialog with
  기본 목록 / 직접 추가 tabs
- offline prerequisite setup: single exe made from PrerequisiteSetup.exe
  (Windows task dialog, no prerequisites) plus every installer, hash
  checked before, while and after appending; optional WebView2 Runtime
  chosen in the save dialog; replaces an existing file only after the
  user agrees (CLI --replace)
- desktop: progress popup with 생성위치 열기, save dialog fix for
  verbatim paths, EXE 서명 and 설치파일 생성 as version tabs, start
  screen 도구 › 서명하기 placeholder
- CLAUDE.md: results are overwritten only with the user's consent
- test kit and scripts for Windows Sandbox and Hyper-V checks
