- Reduce router from 1412 lines to 284 lines (80% reduction)
- Extract all business logic to services/instance_lifecycle.py
- Router now contains only: route definitions, validation, and thin handlers
- Move helpers (_sanitize_name, _generate_instance_name, _modify_compose_file,
_apply_resolved_profile) to services/docker/compose.py
- Zero subprocess calls in router
- All docker references are service imports only
Quality gates: py_compile (pass), file size ≤300 (pass), zero subprocess (pass)
