// TestAutoImportSymlinkedMonorepo verifies that when a monorepo package is symlinked
// into node_modules and imported, auto-imports don't show duplicates.
//
// Scenario:
//   - project-a imports "project-b" via a symlink in node_modules
//   - project-b's source files are at /packages/project-b but symlinked to
//     /packages/project-a/node_modules/project-b
//   - The program contains project-b files via realpath, AND the symlink exists in node_modules
//   - We should NOT see duplicate auto-imports for project-b exports
