This closes PR #8.

[Copilot]

Pull request overview

This PR merges and consolidates the prior “corotational” BPM bond work (PR #8) into bond_style bpm/rotational, adding new runtime options for rotational reference frame and damping construction, plus updated documentation and a new example input.

Changes:

• Extend bpm/rotational with selectable frame (average vs particle) and damping (derivative vs dem) modes and update restart I/O accordingly.
• Remove the separate bpm/corotational bond style implementation files.
• Add a new BPM wire example and update the bond_style bpm/rotational documentation to describe the new keywords and theory.

Few more clean ups here from copilot: jtclemm@99e974c I think that covers everything it said that was correct.

Not sure how to add to this PR, but can just create another PR later.

Thanks, I fetched it from your repo. I also gave you access to mine.

Great, after this PR I think this code is pretty much good to go for an actual pull request whenever you are happy with it and want to proceed.

The only thing I wasn't sure about was how to tag the LAMMPS version in sentence when describing when it changed. But I'd just ask Axel that.
