+/**
+ * Regression tests for issue #1342.
+ *
+ * Bundled plugin scripts use a shebang line (#!/usr/bin/env node or #!/usr/bin/env bun).
+ * If those files are committed with Windows CRLF line endings, the shebang becomes
+ * "#!/usr/bin/env node\r" which fails with:
+ *   env: node\r: No such file or directory
+ * on macOS and Linux, breaking the MCP server and all hook scripts.
+ *
+ * These tests guard against CRLF line endings being re-introduced into the
+ * committed plugin scripts (e.g. by a Windows contributor without .gitattributes).
