Antoine 3289a76e19 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

OP_09: NXOpenSolver Implementation for Hydrotech Beam

Status: COMPLETED — committed as 390ffed

What was done

Completed NXOpenSolver.evaluate() and close() in projects/hydrotech-beam/studies/01_doe_landscape/nx_interface.py.

Implementation pattern

Follows M1_Mirror/SAT3_Trajectory_V7 FEARunner pattern exactly:

create_iteration_folder() — HEEDS-style isolation, copies model + writes params.exp
run_simulation() — journal handles expression import, geometry rebuild, FEM update, solve
Extractor pipeline: displacement → stress → mass

Key technical decisions

Element type auto-detection: Used element_type=None for stress extraction instead of hardcoding CQUAD4. The extractor checks all solid types (CTETRA, CHEXA, CPENTA, CPYRAM) then falls back to shell if needed. This is safer since we haven't confirmed the beam's mesh type.
Mass extraction fallback chain: _temp_mass.txt → _temp_part_properties.json. The solve journal writes both files. The fallback handles edge cases where the primary file is missing.
OP2 naming convention: beam_sim1-solution_1.op2 (lowercase sim stem + lowercase solution name with spaces→underscores). Verified from NXSolver.run_simulation() logic.
Expression unit mapping: All 4 DVs default to mm in _write_expression_file() which is correct for beam_half_core_thickness, beam_face_thickness, holes_diameter. hole_count is unitless but the NX journal's ImportFromFile handles this correctly.
LAC compliance: close() only calls session_manager.cleanup_stale_locks(), never kills NX processes. This follows the LAC critical lesson.
