Fix: Register workspace self-reference symlinks in package map for loose maps

cursoragent · cursoragent · commit aeec360c2249 · 2026-06-19T15:19:51.000Z
When nodePackageMapType is 'loose' and workspace self-reference symlinks
are created by register_workspace_symlinks_at, these entries must be
registered with NodeModulesPackageMapBuilder so they appear in
package_locations_by_node_modules_path. Without this registration,
loose maps miss these workspace locations even though the symlinks exist,
causing resolution failures that wouldn't occur without package maps.
