Duplicated Terragrunt block

Reports duplicated Terragrunt blocks defined at the file root that share the same label (name), such as dependency, feature, generate, include, stack, or unit.

The inspection highlights multiple blocks of the same type that use an identical label. Only top‑level blocks are checked.

Example:

unit "vpc" {
  source = "git::git@github.com:acme/infrastructure-catalog.git//units/vpc?ref=v0.0.1"
  path   = "vpc"
}

# duplicate
unit "vpc" {
  source = "git::git@github.com:acme/infrastructure-catalog.git//units/database?ref=v0.0.1"
  path   = "database"
  values = {
    engine   = "postgres"
    version  = "13"
    vpc_path = "../vpc"
  }
}
