feat: apply v1-based rewrite

[null8626]

The following pull request is a fragment of a larger pull request.

It substitutes all v0 features with v1 ones. And since this change is obviously breaking, the pull request is a major update.

P.S: Due to dependency constraints, the SDK's minimum Go version is 1.25 now.

Looks fine otherwise, just not sure if this is a standard you wanna keep following

[velddev]

These are standardized go comments if i recall correctly. You always start with the value you are documenting

It's worth moving away from Travis, which has been paid for some years now, to GitHub Actions and add golangci/golangci-lint-action to the workflow

Thank you so much for your feedback @kkrypt0nn! ❤️ I didn't touch the project's Travis configuration that much because I have never used Travis before and I didn't want to mess with something I am super not familiar with! I will surely take a look at it!
