Problem

The same personality preset is reused for identical roles across all templates, making organizations feel interchangeable:

• Every senior Backend/Full-Stack Developer = pragmatic_builder (all templates)
• Every mid-level developer = eager_learner (all templates)
• Scrum Master and COO share process_optimizer (agency, full_company)
• UX Designer and UX Researcher both get user_advocate (product_team, full_company)
• Every QA Engineer = quality_guardian or methodical_analyst with no variation

A startup's CTO should feel different from an enterprise CTO. An agency's PM should feel different from a product team's PM.

Proposed Changes

• Vary presets per template so orgs have distinct "feel":
  • Startup CTO: rapid_prototyper (hands-on, fast) vs full_company CTO: systems_thinker (architectural)
  • Agency PM: process_optimizer (delivery-focused) vs product_team PM: strategic_planner (vision-focused)
  • Research lab Backend Dev: independent_researcher vs dev_shop Backend Dev: pragmatic_builder
• Fix role mismatches:
  • Scrum Master should not share preset with COO
  • UX Researcher should be methodical_analyst or independent_researcher, not user_advocate
  • Content Writer in agency could be creative_innovator instead of technical_communicator
• Vary by seniority within templates -- a mid-level dev shouldn't always be eager_learner in every template

Scope

YAML-only changes to src/synthorg/templates/builtins/*.yaml. No new presets needed (20 existing presets are underutilized). Update tests that assert on specific preset values.
