Problem

All 7 builtin templates lean software/tech product development. Two common org archetypes are missing that work with existing roles and require no new tooling:

1. Consultancy -- client-facing advisory/delivery firm. Distinct from agency (which is larger, has creative/marketing). Senior-heavy, project-driven.
2. Data Team -- data-first organization. Distinct from research_lab (which has a Software Architect lead and broader engineering scope). Analytics and ML focused.

Proposed Templates

Consultancy (4-6 agents)

• Software Architect (principal, large) -- technical lead
• Backend Developer x2 (senior, medium) -- delivery
• Project Manager (senior, medium) -- client-facing delivery
• Technical Writer (mid, small) -- documentation/proposals
• Optional: Frontend Developer (mid, small)
• Departments: consulting (head: Software Architect), operations (head: Project Manager)
• Autonomy: supervised (client work = oversight)
• Communication: hierarchical
• Workflow: kanban
• Uses client_advisor preset (feat: add personality presets for new template archetypes #721) for PM
• Budget: ~$60/mo default

Data Team (5-8 agents)

• Data Engineer (senior, medium) -- pipelines
• Data Analyst x2 (mid, medium/small) -- analysis
• ML Engineer (senior, medium) -- models
• Backend Developer (mid, small) -- infrastructure
• Technical Writer (mid, small) -- documentation
• Departments: data_analytics (head: Data Engineer), engineering (head: Backend Developer)
• Autonomy: full (researchers need freedom)
• Communication: event_driven
• Workflow: kanban
• Uses existing data_driven_optimizer, independent_researcher presets
• Budget: ~$55/mo default

Implementation

• Add CONSULTANCY and DATA_TEAM to CompanyType enum
• Create consultancy.yaml and data_team.yaml in builtins/
• Add to BUILTIN_TEMPLATES registry in loader.py
• Add Faker names per agent (consistent with PR feat: replace hardcoded name pools with Faker multi-locale name generation #714 approach)
• Each template uses distinct operational config (not semi/hybrid)
• Add reporting lines and escalation paths (consistent with feat: add reporting lines, escalation paths, and workflow handoffs to templates #719)
• Update tests

Dependencies

• feat: add personality presets for new template archetypes #721 -- new personality presets (provides client_advisor for consultancy PM)
