origin/energy-conservation-poc grew bump-gen/bump-schema --to and update-manifest --gen flags (091b23a) plus a train output-dir date prefix (305e436) after the dwarf unification was written locally. Reconcile: bring plan_bump_gen/plan_bump_schema/plan_update_manifest's target/target_gen support into the plain-function (argparse-free) form, thread --to/--gen through scripts/dwarf.py's bump-gen/bump-schema/ update-manifest commands, and take giant/cli.py's date-prefix change and the associated tests as-is.
