Seven tools matching existing fable-mcp contracts:
- fable_list/get/create/update_project (no delete; archive via status)
- fable_list/create/update_milestone (no get; no delete)
LLM-era similarity-check / 'confirmed' guard for create_project is
NOT replicated — Claude doesn't need it. The service's auto-summary
regeneration side effect (services.projects.update_project) stays
for now; gets removed in Phase 7 along with all other LLM code.
Notable sentinels:
- update_milestone: order_index=-1 means "leave unchanged" (0 is valid)
- create_milestone: description="" becomes None at the service layer
