Reviewer's Guide

This PR updates all gplugins and notebook references from the deprecated gdsfactory.generic_tech API to the newer gdsfactory.gpdk API for layers, layer stacks, simulation settings, and PDK access, without changing functional logic.

File-Level Changes

Change	Details	Files
Switch all plugin and notebook imports from deprecated generic_tech to gpdk equivalents for layers, layer stacks, wafer stacks, simulation settings, and PDK helpers.	Replace gdsfactory.generic_tech.layer_map.LAYER imports with gdsfactory.gpdk.layer_map.LAYER. Replace gdsfactory.generic_tech.layer_stack imports (get_layer_stack, WAFER_STACK, LayerStackParameters, get_process) with gdsfactory.gpdk.layer_stack equivalents. Replace gdsfactory.generic_tech module-level imports (LAYER, LAYER_STACK, get_generic_pdk) with gdsfactory.gpdk equivalents across simulation plugins and tests. Update lumerical simulation settings import from gdsfactory.generic_tech.simulation_settings to gdsfactory.gpdk.simulation_settings. Update all example notebooks to use gdsfactory.gpdk for layers, layer stacks, and PDK activation instead of generic_tech.	gplugins/meshwell/get_meshwell_3D.py gplugins/meshwell/get_meshwell_cross_section.py gplugins/sentaurus/sde.py gplugins/klayout/drc/write_drc.py gplugins/sentaurus/sprocess.py gplugins/common/utils/tests/test_get_component_with_new_port_layers.py gplugins/devsim/doping.py gplugins/devsim/get_simulation.py gplugins/elmer/get_capacitance.py gplugins/elmer/tests/test_elmer.py gplugins/fdtdz/get_epsilon_fdtdz.py gplugins/fdtdz/get_ports_fdtdz.py gplugins/fdtdz/get_sparameters_fdtdz.py gplugins/femwell/test_mode_solver.py gplugins/klayout/dataprep/regions.py gplugins/klayout/drc/check_width.py gplugins/klayout/tests/test_dataprep_regions.py gplugins/lumerical/read.py gplugins/lumerical/write_sparameters_lumerical.py gplugins/meshwell/tests/test_meshwell.py gplugins/palace/get_capacitance.py gplugins/palace/get_scattering.py gplugins/palace/tests/test_palace.py notebooks/elmer_01_electrostatic.ipynb notebooks/fdtdz_01.ipynb notebooks/femwell_02_heater.ipynb notebooks/klayout_dataprep.ipynb notebooks/klayout_drc.ipynb notebooks/lumerical_1_fdtd_sparameters.ipynb notebooks/meep_01_sparameters.ipynb notebooks/meep_02_gratings.ipynb notebooks/meow_01.ipynb notebooks/mode_solver_fdfd.ipynb notebooks/palace_01_electrostatic.ipynb notebooks/palace_02_fullwave.ipynb notebooks/ray_optimiser.ipynb notebooks/sax_01_sax.ipynb notebooks/tidy3d_00_tidy3d.ipynb notebooks/workflow_1_mzi.ipynb
