Replace unreliable emoji flags in the native select with a custom language picker that renders real CSS flag icons, improve retry button naming/tooltips, and keep quick/full e2e coverage green after the UI change.
Introduce a longer smoke-test-full workflow for validating queue, media tools, localization, and reliability flows in one pass, and document both quick and full test commands for contributors.
Expose a single runnable end-to-end test command for fast regression sweeps and update the smoke test to validate preflight and localization-aware clip errors reliably across language modes.
