Pull request overview

This PR refactors the Debye-Grüneisen implementation and its tests, introducing a new plot_vt plotting API and adding a tutorial notebook demonstrating the DebyeGruneisen workflow.

Changes:

• Refactor DebyeGruneisen to use static calculation helpers and add plot_vt() for plotting vs temperature/volume.
• Update tests/test_debye.py to align with the refactor (new plotting API + direct tests for static helpers).
• Add a new example notebook for running DebyeGruneisen in Codespaces and plotting results.

test_plot() expects the pre-process() error message to mention plot(), but DebyeGruneisen.plot_vt() raises DebyeGruneisen.process() must be called before plot_vt(). As written, this regex won’t match and the test will fail. Update the match= pattern to align with the actual plot_vt() error message (or use a looser substring/re.escape).
