Initial commit: DevClaw OpenClaw plugin

Multi-project dev/qa pipeline orchestration with 4 agent tools:
- task_pickup: atomic task pickup with model selection and session reuse
- task_complete: DEV done, QA pass/fail/refine with label transitions
- queue_status: task queue and worker status across projects
- session_health: zombie detection and state consistency checks
