A symlinked files/ or a symlinked directory under it let module check, the merge gate and module add read a template from outside the repository tree, and a symlink no template names passed them while the build's packing refuses it (review of mesh-controller#313). Every entry under files/ must now be a plain directory or file, and templates are read through an os.Root of the module's directory. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
