Further Style Guidelines

Discussed in https://github.com/orgs/RoboLoCo-5338/discussions/149

Originally posted by Advay17 May 5, 2025 One annoying thing about our code (that I am partially a contributor to) is that even though our general style is somewhat unified through spotless, the specific code itself does have discrepancies that I would like to rectify. For instance, our constants don't follow one naming format or another. Another issue is our branch naming, for which we don't have a consistent pattern.

We need to create stricter guidelines on formatting. I suggest that we use checkstyle to enforce this, and will look into installing it onto our repo soon.

See the source discussion for the list of checks I want added.
