fix: unify Windows build on GNU toolchain (RubyInstaller + MSYS2)#419
Merged
Conversation
- Replace standalone msys2/setup-msys2 with RubyInstaller's built-in MSYS2 (ridk exec pacman) to keep toolchain consistent - Set Rust target to x86_64-pc-windows-gnu to match RubyInstaller's MinGW toolchain (eliminates MSVC/GNU mismatch in rb-sys/bindgen) - Remove MSYS2 env overrides (CPATH, BINDGEN_EXTRA_CLANG_ARGS, etc.) - Fix Linux/Windows verify step to use bundle exec for load path Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Windows gem ビルドの MSVC/GNU ツールチェーン不一致を修正。
根本原因:
ruby/setup-rubyは RubyInstaller (MinGW/GNU) を使うが、Rust のデフォルトターゲットがx86_64-pc-windows-msvcであるため、rb-sysの bindgen が MSVC の sysroot を探してstrings.hnot found エラーになっていた。修正: 「混ぜるな危険」の原則に従い、GNU ツールチェーンに統一。
msys2/setup-msys2→ RubyInstaller 内蔵の MSYS2 (ridk exec pacman)x86_64-pc-windows-gnuを明示指定CPATH,BINDGEN_EXTRA_CLANG_ARGS等）を全て削除bundle exec rubyに修正（ロードパス解決）Related Issues
