Improve caching

[rmarescu]

What

• Create one cache file per test <TIMESTAMP>—<SHA-1>.json
  • Having a timestamp associated should make it easier for the developer to find a test, and to purge cache chronologically
  • Use the first 8 characters of the SHA-1 value
• Create a folder with the same name of the cache file to store the screenshots

  .shortest/cache/2025-01-07T04-40-01-311Z-a79d4f5a.json
  .shortest/cache/2025-01-07T04-40-01-311Z-a79d4f5a/*.png
  

• Consider using cache versioning prefix for breaking changes
  • With certain versions the cache may break, so this would allow to migrate easily, multiple versions can coexist, easy rollback, no manual cache cleanup needed between versions

Why

With caching, it's difficult to tell which screenshots are associated with a given test. The screenshots should be somehow associated with the cached test.
All cached tests are stored in a single file cache.json. With a project that has many tests, I think that could cause problems. Also, is hard to find and debug a given test.
