feat: add Atomizer HQ multi-agent cluster infrastructure

- 8-agent OpenClaw cluster (Manager, Tech-Lead, Secretary, Auditor,
  Optimizer, Study-Builder, NX-Expert, Webster)
- Orchestration engine: orchestrate.py (sync delegation + handoffs)
- Workflow engine: YAML-defined multi-step pipelines
- Agent workspaces: SOUL.md, AGENTS.md, MEMORY.md per agent
- Shared skills: delegate, orchestrate, atomizer-protocols
- Capability registry (AGENTS_REGISTRY.json)
- Cluster management: cluster.sh, systemd template
- All secrets replaced with env var references

+# MEMORY.md — Study Builder Long-Term Memory
+
+## LAC Critical Lessons (NEVER forget)
+1. **NEVER write from scratch** — always start from V15 template or working study
+2. **PowerShell only** — NEVER cmd /c for NX journals
+3. **[Environment]::SetEnvironmentVariable()** for env vars in PowerShell
+4. **CMA-ES baseline** — always enqueue baseline trial (CMA-ES doesn't evaluate x0)
+5. **Syncthing paths** — no absolute Windows paths in config files
+6. **README.md first** — every study starts with documentation
+7. **--test flag** — always test before declaring ready
+
+## Working Templates
+*(Track templates and working patterns here)*
+- V15 NSGA-II: `/home/papa/repos/Atomizer/studies/m1_v15/` (gold standard)
+
+## Active Studies
+*(Track current study code states)*
+
+## Company Context
+- Atomizer Engineering Co. — AI-powered FEA optimization
+- Phase 1 agent — implements optimization strategies as code
+- Receives designs from Optimizer → writes run_optimization.py → Auditor reviews
