Manual chooser-column filtering (SIMULATE/LOGSUM_CHOOSER_COLUMNS) was a memory workaround that is now redundant: drop_unused_columns in ComputeSettings (default True) prunes DataFrame columns automatically one layer beneath each model function. Remove all the FIXME blocks and the household_id patch-ups they contained. Deprecate SIMULATE_CHOOSER_COLUMNS and LOGSUM_CHOOSER_COLUMNS in all settings classes so existing YAML configs emit DeprecationWarning instead of failing. Also wire state.get_global_constants() into locals_d at every utility- evaluation site (_location_sample, run_location_simulate, _destination_sample, run_destination_simulate, _od_sample, run_od_simulate, _schedule_tours) so global constants are available in @ expressions in CSV specs. Closes ActivitySim#1017 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
SIMULATE_CHOOSER_COLUMNS/LOGSUM_CHOOSER_COLUMNSmemory hacks): allFIXME - MEMORY HACKblocks andhousehold_idpatch-ups are deleted fromlocation_choice.py,tour_destination.py,tour_od.py,tour_scheduling.py, andschool_escorting.py. Memory pruning is now handled automatically byComputeSettings.drop_unused_columns(defaultTrue) insideinteraction_sample/interaction_sample_simulate.SIMULATE_CHOOSER_COLUMNSandLOGSUM_CHOOSER_COLUMNSin all settings classes (TourLocationComponentSettings,TourModeComponentSettings,SchoolEscortSettings,TourSchedulingSettings) — existing YAML configs emit aDeprecationWarninginstead of failing.state.get_global_constants()is now injected intolocals_dat every utility-evaluation site (_location_sample,run_location_simulate,_destination_sample,run_destination_simulate,_od_sample,run_od_simulate,_schedule_tours) so global constants are available in@-prefixed CSV spec expressions.Closes #1017
