Implement Origin Curation Feature (#1932)

Overview

Adds comprehensive origin review, curation, propagation, and deployment capabilities to ScanCode.io, enabling manual review of automated origin determinations and publishing curated results to FederatedCode.

Key Features

• Review Interface: Filterable dashboard with bulk actions for approving/rejecting relations
• Manual Curation: Detail views for editing curation status, confidence levels, and notes
• Propagation: Automated strategies (similarity, directory, package, pattern) to extend trustworthy signals
• Deployment: Export curated relations to FederatedCode with merge strategies
• Audit Trail: Complete history tracking via OriginCuration model

Changes

Models & Database

• scanpipe/models.py - Added OriginCuration and PropagationBatch models, extended CodebaseRelation with curation fields
• scanpipe/migrations/0077_add_origin_curation.py - Migration for new models and fields

API

• scanpipe/api/views.py - Added relations, relation_detail, relations_bulk_curate endpoints
• scanpipe/api/serializers.py - Added curation serializers with history tracking

UI & Views

• scanpipe/views.py - Added OriginReviewView, OriginCurateView, OriginCurateCreateView, OriginPropagateView, OriginDeployView, OriginBulkCurationView
• scanpipe/forms.py - Added curation forms (OriginCurationForm, BulkCurationForm, OriginPropagationForm, OriginDeployForm)
• scanpipe/filters.py - Added curation filters
• scanpipe/urls.py - Added origin curation routes

Templates

• scanpipe/templates/scanpipe/origin_*.html - Review, curate, propagate, deploy pages
• scanpipe/templates/scanpipe/tabset/tab_curation*.html - Curation detail tabs
• scanpipe/templates/scanpipe/modals/origin_bulk_curation_modal.html - Bulk actions modal
• Updated project_detail.html and relation_list.html with origin review links

Pipes & Logic

• scanpipe/pipes/origin_propagation.py - Propagation strategies implementation
• scanpipe/pipes/federatedcode.py - Export and merge functions for origin curations
• scanpipe/pipelines/publish_to_federatedcode.py - Integration with deployment pipeline

Documentation

• docs/api/origin-curation-api.rst - REST API reference
• docs/origin-curation-guide.rst - User guide
• docs/tutorial_origin_curation_workflow.rst - Step-by-step tutorial
• docs/developer/origin-curation-architecture.rst - Architecture documentation
• docs/index.rst - Added documentation links

Tests

• scanpipe/tests/test_api.py - API endpoint tests
• scanpipe/tests/test_views.py - View tests
• scanpipe/tests/test_models.py - Model tests
• scanpipe/tests/test_pipelines.py - Pipeline tests
• scanpipe/tests/pipes/test_*.py - Pipe tests

Approach

The implementation follows a layered architecture: data models with audit trails, UI forms/views for user interaction, REST API for automation, and background pipes for propagation/deployment. All curation actions create OriginCuration history records for full traceability.
