test: Phase 99 add trailing backslash escape best-effort (VM+LLVM)
末尾バックスラッシュ処理: - 現行仕様: best-effort（そのまま出力）として固定 - fixture: "hello\\" → "hello\" を出力 - VM+LLVM EXE parity完全対応 Integration smokeで検証済み 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
