Problem

The setup wizard shows templates as a flat list of cards with name + description. Users pick one and move on. There's no way to compare templates, estimate costs, or understand the org structure before committing.

Proposed Changes

Template comparison

• Side-by-side view showing: agent count, department count, estimated monthly cost, autonomy level, communication pattern
• Highlight differences between selected templates

Cost estimator

• Given configured providers (from the previous setup step), estimate monthly cost per template based on model tier assignments and provider pricing
• Show cost breakdown by department

Category grouping

• Group templates: "Small Teams" (solo_founder, startup), "Specialized" (dev_shop, research_lab, product_team, consultancy, data_team), "Full Organizations" (agency, full_company)
• Visual separation in the template grid

Template preview

• When a template is selected, show a mini org chart preview (departments, agent count per department, hierarchy) before committing
• "Recommended" badge based on configured provider model tiers (e.g. if only small models available, recommend solo_founder/startup)

Relationship to #238

This can be implemented as part of the builder wizard (#238) or as a standalone enhancement. The scope here is specifically the template selection UX within the Company step.
