Terraform Resource Block Header in PY
Match the opening line of a Terraform `resource "type" "name" {` block, capturing the resource type and local name.

How the pattern works
resource\s+ matches the keyword and required whitespace. "([\w\-]+)" captures the resource type (e.g. `aws_instance`). "([\w\-]+)" captures the local name. The trailing `\s*\{` confirms a block opener (so we don't match string-literal `resource "x" "y"` in a comment).
Examples
Input
resource "aws_s3_bucket" "main" { bucket = "my-app" }Matches
resource "aws_s3_bucket" "main" {
Input
resource "google_storage_bucket" "backups" {Matches
