Extract onboarding flow step resolution and async runner logic into a
dedicated module for better separation of concerns and maintainability.
Refactor context/provider to use new helpers and simplify settings modal
control. Add unit tests for onboarding step resolution and async runner
coalescing. Update e2e helpers and selectors for onboarding modals.
Adjust environment file handling for CI and Docker contexts.
- Add .dockerignore for build hygiene
- Refactor onboarding context and modal logic
- Add src/lib/client/onboarding-flow.ts with core onboarding helpers
- Add onboarding-flow unit tests
- Update Playwright config and scripts for CI env loading
- Improve test selectors for claim modal
- Update .gitignore to exclude all .env* except .env.example
This change increases onboarding logic modularity and reliability, and improves CI/test environment handling.
