Terragrunt catalog TUI reports `terragrunt.hcl` scaffolded when boilerplate template generates a different file

Describe the bug

When scaffolding a boilerplate template from the terragrunt catalog TUI, the post-scaffold success message refers to the wrong output file. It reports that terragrunt.hcl was scaffolded, even when the template actually generates different files and there are no terragrunt.hcl among them.

Steps To Reproduce

Catalog scaffold success message for boilerplate templates (gruntwork-io/terragrunt).

1. In an empty directory (or any directory where you want the scaffold output), run:

   bash复制

   terragrunt catalog github.com/Nerdeez/terragrunt-catalog

2. In the catalog TUI, open Templates and select a boilerplate template, for example:

   • Live root template (templates/root) — generates root.hcl
   • config (templates/config) — generates files under config/ (not terragrunt.hcl)

3. Press s to scaffold into the current directory (.).

4. Complete the scaffold prompts (fill in template variable values).

5. Observe the success message shown after scaffolding completes.

6. List the files that were actually created in the output directory (e.g. ls -la).

Expected behavior

After scaffolding a boilerplate template from the catalog TUI, the success message should reflect what was actually created—not assume terragrunt.hcl.

For example, when scaffolding the Live root template from github.com/Nerdeez/terragrunt-catalog, the message should indicate that root.hcl was generated (and any dependency outputs, such as config/), e.g.:

root.hcl scaffolded

./root.hcl
./config/common.hcl
./config/billing.hcl
./config/region.hcl

When scaffolding the config template alone, the message should list the files under config/ that were created, not terragrunt.hcl.

In general, the post-scaffold callout should name the file(s) produced by the template (or say something like “template scaffolded successfully” with an accurate list of generated paths), so users are not directed to open a file that does not exist.
