Defines the discovery phase facilitation feature:
- Per-trace structured view with 5 category buckets
- Real-time classification of participant findings
- Facilitator-controlled question generation (broadcast per trace)
- Auto-detected disagreements between participants
- Promotion workflow to draft rubric staging area
- Fuzzy progress for participants (no category bias)

Complete implementation of the Assisted Facilitation v2 architecture across all 6 phases:

Phase 1: Database & Models
- Added 5 new database tables (ClassifiedFinding, Disagreement, TraceDiscoveryQuestion, TraceDiscoveryThreshold, DraftRubricItem)
- Added corresponding Pydantic models with proper configuration
- Updated relationships in WorkshopDB and TraceDB

Phase 2: Classification Service
- Created ClassificationService with real-time finding classification
- Added DSPy signatures for ClassifyFinding and DetectDisagreements
- Implemented local classification heuristic (placeholder for LLM)

Phase 3: Discovery Service Updates
- Added 6 new methods: submit_finding_v2, get_trace_discovery_state, get_fuzzy_progress, promote_finding, update_trace_thresholds
- Implemented fuzzy progress (exploring/good_coverage/complete) for participants
- Added structured discovery state for facilitators

Phase 4: API Endpoints
- Added 7 new REST endpoints for assisted facilitation v2
- Endpoints cover findings submission, discovery state, promotion, and threshold updates

Phase 5: Client Updates
- Created TraceDiscoveryPanel component for facilitator view
- Created DraftRubricPanel component for promoted findings
- Added 5 new React hooks to useWorkshopApi.ts

Phase 6: Testing
- Created test_classification_service.py with 7 tests (all passing)
- Created test_discovery_service_v2.py with 6 tests (all passing)
- 100% test pass rate (13/13 tests)

Key Features:
- Real-time finding classification (5 categories)
- Fuzzy progress indicator for participants
- Disagreement detection framework
- Draft rubric staging area
- Per-trace threshold management

- Add .withRealApi() to all TestScenario builders so tests use real database
- Add @SPEC:ASSISTED_FACILITATION_SPEC tag to all 5 test files
- Add ASSISTED_FACILITATION_SPEC to known specs in analyzer and docs
- Fix justfile to export E2E_API_URL for dynamic port support

Resolve conflicts by merging both feature sets:
- Keep assisted facilitation v2 features (discovery questions, classification)
- Keep JSONPath display customization features
- Merge database columns: discovery_questions_model_name + input/output_jsonpath
- Merge frontend hooks for both feature sets
- Update SPEC_COVERAGE_MAP with both RUBRIC_SPEC and TRACE_DISPLAY_SPEC updates
