chore: convert all relative imports to absolute imports (#29)

## Description

This is a small PR that does some cleanup I wanted to do for a while:

- Converted all relative imports to absolute imports
- Added a rule against this:
https://docs.astral.sh/ruff/rules/relative-imports/

Relative imports are not bad, it's just that absolute imports are nicer,
at least to me :)
