API Changes

• BeamLine.glow() now accepts mode='dynamic' or mode='static'.
• The old v2= argument remains temporarily supported for compatibility and emits a deprecation warning.
• Energy-based auto-alignment for pitch and bragg now accepts unit strings, for example pitch='8 keV', bragg='8000 eV', or 'auto'.
• The older list form, such as bragg=[8000], remains supported for compatibility and emits a deprecation warning.
