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

+## Material Properties
+
+- **Zerodur**: Density is 2.53 g/cm³, Thermal Conductivity is 1.46 W/(m·K), Poisson's Ratio is 0.243.
+- **Clearceram-Z**: CTE is 0.02 μstrain/°C (-60 to 160 °C), Density is 2.55 g/cm³. Note: Standard grade, not HS.
+- **Clearceram-Z HS**: CTE is 0.0 ± 0.2 x 10⁻⁷ /°C, Density is 2.55 g/cm³.
+- **Corning ULE 7972**: CTE is 0 ± 30 ppb/°C (5-35°C).
+- **Invar 36**: Young's Modulus is ~141 GPa (annealed).
+
+## Research Summaries
+
+- **Clearceram-Z HS vs. Zerodur for Large Mirrors**: Both are top-tier materials. Zerodur has extensive flight heritage (VLT, Keck) and a deeply characterized CTE. Clearceram-Z HS shows potentially superior stability under thermal cycling and was chosen for the TMT, making it a strong choice for next-generation ground-based telescopes where this is critical.
