catalog-redesign — Templates and .terragrunt-catalog-ignore

The catalog-redesign experiment picked up user-visible improvements to discovery and filtering.

Discovery walks the entire repository instead of only a modules/ directory, so modules and templates can live anywhere in the tree. Boilerplate templates (directories containing a .boilerplate/ subdirectory or a top-level boilerplate.yml) are discovered as a distinct component kind alongside OpenTofu/Terraform modules and labeled as templates in the UI. When a directory qualifies as both, it is classified as a template.

Catalog authors can commit a .terragrunt-catalog-ignore file at the repo root to keep directories such as examples/ or test/ out of discovery. The file uses .gitignore-style semantics: one pattern per line, # for comments, ! for negation, and last match wins. Matching is anchored at the repo root; a lone * does not cross /, and ** does.

# .terragrunt-catalog-ignore
examples
examples/**
test/**
!test/keep

An --ignore-file flag (also available via TG_IGNORE_FILE) points at an additional ignore file that is layered on top of the repo's .terragrunt-catalog-ignore. The extra rules are appended under last-match-wins semantics, so the flag can either add new exclusions or re-include paths that the repo file excluded.

The list view is split into All, Modules, and Templates tabs, with All selected on launch so every discovered component is visible without switching views. Press tab and shift+tab to cycle between them; each tab keeps its own cursor and search filter.
