Catalog Redesign

catalog-redesign — Units and stacks, scaffolded values, and key-binding cleanup

The redesigned terragrunt catalog TUI gains two new component kinds, a guided scaffolding flow for placing them, and a small key-binding cleanup.

Units and stacks join modules and templates

Catalog discovery now classifies units (directories containing a terragrunt.hcl) and stacks (directories containing a terragrunt.stack.hcl) as first-class component kinds, alongside OpenTofu/Terraform modules and boilerplate templates. The list view picks them up automatically and they appear under their own tabs; press tab and shift+tab to cycle.

When more than one classification could apply to the same directory (for example, a stack directory that also contains a unit), Terragrunt resolves it to a single kind under a fixed precedence: template, stack, unit, module.

Copy and scaffolded values

Selecting a unit or stack from the catalog now offers a copy action that materializes the component into your working directory. Terragrunt walks the copied component for values.<name> references and, if it finds any, writes a sibling terragrunt.values.hcl stub. Names referenced outside a try(...) are listed as required with a "TODO" placeholder; names referenced through a try(...) are listed as optional, pre-populated with the literal default from the fallback. An existing terragrunt.values.hcl is left alone.

After the TUI exits, Terragrunt prints a short callout pointing at the directory it wrote to and any follow-up command you need to run, instead of leaving you to find the new directory yourself.

Catalog key bindings

The ctrl+j binding on the catalog list has been removed in favor of enter alone for choosing a focused entry, and dropped from the navigation set used while filtering. The mini help footer is updated to match.
