Local name collisions in generated group caps

[jimmielin]

Description

Two schemes in the same suite group cap using the same name for arguments that have different meanings (i.e., different standard name) might generate group cap that is uncompilable. See #771 for reproducer

Steps to Reproduce

sima_2026-07-15 in CAM-SIMA

capgen v0

Reproducer in #771

Two schemes, same argument name, one is constituent, another is a normal quantity. At least this situation will trigger the bug, possibly others.

Additional Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

former defines it as

[ ni ]
  standard_name = mass_number_concentration_of_ice_wrt_moist_air_and_condensed_water
  units = kg-1
  type = real | kind = kind_phys
  dimensions = (horizontal_loop_extent, vertical_layer_dimension)
  intent = in
  advected = True

latter defines it as

[ ni ]
  standard_name = brunt_vaisalla_frequencies_at_interfaces
  units = s-1
  type = real | kind = kind_phys
  dimensions = (horizontal_loop_extent, vertical_interface_dimension)
  intent = in

Can you clarify if this is with capgen v0 or v1?
