chore: add rabi-chevron (precommit compliant)

[Kyung-hoon-Jung0]

Summary

This PR focuses solely on pre-commit (pylint/black) compliance for newly added calibration files.

• No functional or behavioral changes
• Only docstrings, minor typo/formatting fixes, and explicit pylint rule handling
• Goal: ensure clean pre-commit passes and reduce reviewer burden

Reviewer note

GitHub shows all lines as changed because these files are newly added to the KAVR_12182025 branch.
To avoid a full line-by-line review, the changes below are organized by file, summarizing all intentional, non-functional modifications.

• All files now pass the project's pylint checks via pre-commit
• The remaining local-module import warning (quam_config) is expected and already explicitly disabled
• No logic, algorithm, or runtime behavior was modified
