Code Review
This pull request introduces a self-cleaning service worker to replace the previous caching service worker, which is a significant and positive simplification. The changes are extensive, affecting the Flutter tool, flutter.js, and various test files. The new service worker's role is to unregister itself and reload clients, effectively removing the old caching behavior. The logic in flutter.js is cleverly updated to only register this new worker if an old one is detected, ensuring a smooth transition for existing applications while not affecting new ones. The test suite has been appropriately refactored with a new integration test that validates this cleanup mechanism. The implementation is solid, but I have one suggestion to improve the robustness of the test code.

This is great; I only have a small comment in the code of the cleanup service worker about refreshing "too many" tabs and to follow the workbox example. But all my comments are nits, or unrelated to this specific change. LGTM!

IIRC the promise-based initialization has been warning a "use callbacks" message for a few years now, consider removing it!

There was a problem hiding this comment.
The warning was added because the promise-based API has issues with hot restart (context: #108776).
I imagine the same issue still exists today, so the warning is still valid.

Introduce a self-cleaning service worker to replace the old one. Previous attempts (flutter#170918, flutter#173609) had (accidentally?) disabled the loading of the service worker in `flutter.js`. This PR preserves the logic for loading the service worker, and it prints a deprecation warning. Towards flutter#156910 Closes flutter#106225
