feat(tui): skip IaC caches (.terraform, .terragrunt-cache, ...) in recursive @-search

Add Terraform/Terragrunt/Pulumi/Serverless/CDK provider and module
caches to the recursive walk skip list. These hold copies of
downloaded providers and generated module trees that would otherwise
dominate the entry budget with non-source files.
