What I did

Changed the default hashing algorithm for the file system cache from MD5 to SHA256, as FIPS environments don't allow the usage of insecure hasing algorithms like MD5.

Using Storybook in a FIPS environment would result in an error like:

  throw error;
  ^

Greptile Summary

Updates FileSystemCache to use SHA256 instead of MD5 for FIPS-compliant environments, addressing compatibility issues with secure computing standards.

• Modified code/core/src/common/utils/file-cache.ts to replace MD5 with SHA256 hashing algorithm
• Resolves runtime errors in FIPS environments where MD5 is disabled as an insecure algorithm
• Existing caches using MD5 will need to be regenerated with the new SHA256 algorithm
• Change improves security while maintaining cache functionality
• No breaking changes to the cache API, only internal hashing implementation changed
