- Rewrite scripts/run-migrations.js for PostgreSQL (was better-sqlite3)
- Rewrite scripts/load-initial-data.js for PostgreSQL (was better-sqlite3)
- Make db connection lazy in src/lib/db/index.ts to avoid build-time errors
when DATABASE_URL is not available in Docker build stage
- Add scripts/run-migrations.js to run migrations before data loading
- Fix startup.sh ordering: migrations -> data load -> app start
- Fix migration 0005 missing statement-breakpoint between ALTER TABLE statements
- Add migration 0005 to drizzle journal (was missing)
- Fix load-initial-data.js to check table existence before querying
- Fix load-initial-data.js to create chart record before inserting candles (chart_id NOT NULL constraint)

- Add pre-migration check for inconsistent DB state (tables without migration tracking)
- Add GET /api/span-annotations/export endpoint for ML pipeline JSON/CSV export
- Add source and model_prediction fields to span_annotations schema
- Update POST endpoint to accept source (human/model/human_correction) and model_prediction metadata
- Support negative annotations (label 'O' for user corrections to model predictions)
- Create migration 0005 for new schema fields
Completes tasks 8.1-8.4 of candle-backend change
