Catalog Redesign Scaffold Path Traversal

catalog-redesign — Scaffolding a component no longer fails with a path-traversal error

Scaffolding a component from the catalog (pressing s) could fail on macOS while downloading the source:

subdirectory component contain path traversal out of the repository

The catalog caches each repository under the system temporary directory, which macOS reports through a symlink (/var/folders/... pointing at /private/var/folders/...). The source location Terragrunt handed to the downloader was built against the unresolved path, so it pointed outside the cached repository and was rejected.

Terragrunt now resolves the temporary directory before discovering components, so the source stays inside the repository and scaffolding proceeds.
