chore: add ramsey with precommit compliant

[Kyung-hoon-Jung0]

Summary

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

• No functional or behavioral changes
• Added missing docstrings for modules, classes, and functions
• Fixed import order, line length, and code style issues
• Goal: ensure clean pre-commit passes

File-by-file summary of changes (non-functional only)

calibration_utils/ramsey/__init__.py

• Added module docstring: "Ramsey experiment utilities for qubit characterization."

calibration_utils/ramsey/analysis.py

• Added module docstring: "Analysis utilities for Ramsey experiment: fitting frequency offset and T2* decay."
• Added function docstring for process_raw_dataset (line 48): "Convert IQ data to voltage if state discrimination is not used."
• Updated class docstring for FitParameters (line 14): Changed from "qubit spectroscopy" to "Ramsey experiment" for accuracy

calibration_utils/ramsey/parameters.py

• Added module docstring: "Parameter definitions for Ramsey experiment."
• Added class docstring for NodeSpecificParameters (line 8): "Ramsey-specific parameters for frequency detuning and averaging."
• Added class docstring for Parameters (line 21): "Combined parameters for Ramsey calibration node."

calibration_utils/ramsey/plotting.py

• Added module docstring: "Plotting utilities for Ramsey experiment visualizations."
• Replaced dict() call with dict literal {} (line 138)
  • Changed bbox=dict(facecolor="white", alpha=0.5) to bbox={"facecolor": "white", "alpha": 0.5}
• Updated function docstring for plot_raw_data_with_fit (line 16): Changed from "resonator spectroscopy" to "Ramsey oscillations" for accuracy
• Updated plot title (line 41): Changed from "Qubit spectroscopy" to "Ramsey oscillations" for accuracy

calibrations/1Q_calibrations/06a_ramsey.py

• Added module docstring: "Ramsey calibration for qubit frequency and T2* measurement." (line 1)
• Fixed import order (lines 1-7):
  • Moved from dataclasses import asdict to standard library import section (before third-party imports)
• Fixed long docstrings by splitting lines (lines 170, 208):
  • execute_qua_program: Split into two lines
  • analyse_data: Split into two lines
• Added function docstring for custom_param (line 56)
• Added function docstring for save_results (line 249): "Save all node results and state updates."
