gohawk lab — Rabbit Hole Series
===============================
A four-package Go module, one planted lifecycle bug per package:

  cmd/lab/main.go              lockorder/missing-release
  internal/metrics/metrics.go  resourcelifetime/missing-release
  internal/pipeline/pipeline.go goroutineownership/unjoined
  internal/worker/worker.go    concurrentcapture/shared-capture

Reproduce:
  1. bash setup.sh /tmp/gohawk-lab
  2. copy main.go, metrics.go, pipeline.go, worker.go into the paths above
  3. re-run:  /tmp/gohawk-lab/bin/gohawk ./...

go test and go vet both pass on this code. gohawk reports all four.
Tested with gohawk v0.7.2, Go 1.27.3, staticcheck 2026.2.2.
