fix: handle diff-sequences import issue

[luxass]

This PR fixes the error TypeError: diff is not a function after converting to ESM-only in v2.0.0.

The diff-sequences package exports { default: function } in ESM but the function directly in CommonJS. Added dynamic detection to handle both cases.

Hi @ota-meshi, I have the same "diff" issue since 2.0 with this project / config: https://github.com/OlivierZal/com.melcloud.extension/blob/main/eslint.config.js (uncomment the commented rules to see that ESLint crashes).

Thank you!
