spec(005): Add comprehensive implementation plan for Bulk Operations
Adds:
- plan.md: Technical context, constitution check, phases
- research.md: 7 research decisions (progress tracking, chunking, type-to-confirm)
- data-model.md: BulkOperationRun model, schema changes, query patterns
- quickstart.md: Developer onboarding, testing workflows, debugging
Key Decisions:
- BulkOperationRun model + Livewire polling for progress
- collect()->chunk(10) for memory-efficient processing
- Filament form + validation for type-to-confirm
- ignored_at flag to prevent sync re-adding deleted policies
- Eligibility scopes for safe Policy Version pruning
Estimated: 26-34 hours (3 phases for P1/P2 features)
Next: /speckit.tasks to generate task breakdown
